Glossary:
MOID = Minimum Orbit Intersection Distance, or how close the object and the Earth can come if the timing is just right (or wrong).
PHA = Potentially Hazardous Asteroid, brighter than H=22 with a MOID less than 0.05 AU
  1. 2024 EO2, an NEO discoverd by WISE at ecliptic latitude 66 degrees, has a MOID of 0.1925 AU and a perihelion at 1.1848 AU. The eccentricity (e = 0.56) and inclination (i = 54 deg) are both fairly high.
  2. 2024 AP7, an Apollo with a perihelion at 0.5895 AU and a MOID of 0.2274 AU. The eccentricity is 0.675 and the period 2.45 years. The probable diameter is several hundred meters.
  3. 2024 AF6, an Aten with a perihelion at 0.4296 AU and aphelion at only 1.0211 AU. The MOID is 0.1343 AU for Earth, but only 0.01495 AU for Venus. WISE discovered this near the South ecliptic pole at latitude -76.
  4. 2023 YH2, an Aten with a MOID of only 0.0138 AU and a perihelion at 0.6410 AU. The period is 0.85 years. Given the range at detection it is probably bigger than 140 meters in diameter but with a low albedo so it is too faint optically to be classified as a PHA.
  5. 2023 YN1, an NEO with a rather eccentric orbit (e=0.60), a period of 5.69 years and perihelion at 1.26 AU. This has a rather low albedo and a diameter of about 0.5 km. Seen by Pan-STARRS on 4 separate nights but not linked until WISE got a long tracklet with 12 observations. The MOID is 0.29 AU.
  6. 2023 WE3, a PHA with a MOID of 0.0199 AU and a perihelion at 0.8856 AU. The period is 3.29 years and the eccentricity is high at 0.60. Given the range at detection the diameter is probably several hundred meters.
  7. 2023 WY2, an NEO with a MOID of 0.2412 AU and a perihelion at 1.0537 AU. The period is 10.3 years, so the eccentricity is large at 0.78. The orbit crosses the Mars and juptier orbits. The diameter is probably several hundred meters.
  8. 2023 VV2, an NEO with a MOID of 0.0275 AU and perihelion at 1.0201 AU. It is not a PHA because it is too faint optically. The period is given as 2.66 years so it may be in archived data from 2015. Pan-STARRS also saw this object on 4 Nov 2023.
  9. 2023 QR6, an eccentric NEO with perihelion at 0.5207 AU, so its crosses the orbits of Mars, Earth and Venus. It's fairly bright with H=18.03, but the MOID is 0.3257 AU.
  10. 2009 SQ, a very eccentric NEO with eccentricity e=0.86 and a period of 4.46 years, recovered by WISE on 10 Jun 2023 at a position 2 degrees from the prediction after not being seen for 14 years. The MOID is 0.2795 AU and the perihelion is at 0.3782 AU.
  11. 2023 KU5, an Earth and Mars crosser with an eccentricity of 0.62 and a period of 3.8 years. The perihelion in 0.9186 AU and the MOID is 0.0581 AU. First seen by Pan-STARRS, then WISE, then LPL/Spacewatch II for a 4 day observed arc.
  12. 2023 CE4, has a MOID of 0.0487 AU and perihelion at 0.9480 AU. The optical brightness is not high enough to get listed as a PHA, but since WISE detected it at a range of 0.23 AU it is probably bigger than 140 m with a low albedo.
  13. 2022 YL7, probably the last NEO to be discovered by WISE in 2022 (the "Z" half month does not exist), has a very eccentric orbit (e = 0.77) that crosses the orbits of Mars, Earth, Venus and Mercury. The perihelion is 0.2719 AU while the MOID is 0.2015 AU. The MOID with Mercury is only 0.0031 AU and with Venus 0.0251 AU. The comet-like orbit suggests it might be active near perihelion which is coming 26 Feb 2023.
  14. 2022 XG2, an NEO found by WISE on 12/11/22 at -45 deg declination and -55 deg ecliptic latitude, and then observed at CTIO 10 days later at -25 deg declination. The range when detected by WISE was ~0.35 AU so this is at least a few hundred meters in diameter. The perihelon is at 0.9305 AU and the MOID is 0.2672 AU.
  15. 2022 WY14 is a bright NEO with a perihelion at 0.5526 AU and a MOID of 0.4580 AU. The orbit is quite eccentric with e=0.7995 and the inclination is large at 37 degrees.
  16. 2022 WO14 has period of 4.01 years, a MOID of 0.1503 AU, and a perihelion of 1.1405 AU.
  17. 2022 VL2, discovered by Pan-STARRS but confirmed by WISE, has a MOID of 0.2608 AU and a perihelion at 1,2328 AU.
  18. 2022 UX35, is fairly large but just barely an NEO with a perihelion at 1.2978 AU. The MOID is 0.4843 AU so this is not a hazard to the Earth. The eccentricity is fairly large at 0.556 and the inclination is 19.1 degrees. The period is 5.00 years so it may be present in data taken 5 years ago.
  19. 2022 TO2, an NEO with perihelion at 0.7463 AU and a MOID of 0.1649 AU. It was discovered in the far Southern sky, at a range of Delta = 0.55 AU, so it is probably several hundred meters in diameter and low albedo.
  20. 2022 TP2, a PHA with a perihelion at 0.9796 AU and a MOID of 0.0247 AU. The period is 4.00 years which suggests it could have been seen in 2014 and 2018. The optical brightness is just above the minimum for a PHA, but the range at detection suggests it is low albedo and well above 140 meter diameter.
  21. 2022 SQ48, an NEO with perihelion at 1.1428 AU and a MOID of 0.2335 AU. The eccentricity is fairly large at 0.59 so the period is 4.63 years. WISE discovered this in the Southern sky at -55 degrees declination.
  22. 2022 PK2, a fairly large NEO with perihelion at 1.0992 AU and a MOID of 0.1887 AU. The eccentricity is fairly large (0.63) and the period is 5.05 years. Since it is fairly bright in the infrared at a fairly long range, the best fit model has a diameter of 866 meters.
  23. 2022 PG2, an Earth and Mars crosser with a MOID of 0.033 AU, and a perihelion at 0.9738 AU. The period is 4.75 years. The optical brightness gives an H absolute magnitude of 22.8, too faint to be a PHA, but the albedo is probably quite low (about 4 percent) based on the IR data with a diameter over 140 meters but uncertain due to the high phase angle of the observations.
  24. Comet C/2022 P1 (NEOWISE), a retrograde comet with perihelion at 1.597 AU and an inclination of 154.5 degrees. The period is approximately 60 years.
  25. 2022 OZ9, an eccentric (e=0.56) NEO with a perihelion at 1.1836 AU and a MOID of 0.1824 AU, discovered by WISE at a range of 0.6 AU.
  26. 2022 MK5, a PHA with a MOID of 0.0273 AU and a perihelion at 1.0395 AU. The eccentricity is 0.53 and the period is 3.30 years. This is a low albedo object with diameter of 250 ± 75 meters.
  27. P/2016 PM1 (WISE-PANSTARRS), cometary activity reported in 2016 PM1, so it becomes another WISE comet. This has a perihelion at 1.47 AU, so it is not an NEO.
  28. 2022 KR7, an eccentric NEO with e=0.65, a MOID of 0.1454 AU, and perihelion at 1.0400 AU. WISE discovered it at a range of 0.25 AU, but its optical absolute magnitude is only 22.88, so this is probably about 2-300 meters in diameter and low albedo.
  29. 2022 JV2, a highly eccentric NEO with e=0.77 and a perihelion at 0.7347 AU. The MOID is 0.1030 AU.
  30. 2019 XU14, observed 92 times by WISE between 3 Dec 2019 and 4 Jan 2020 but just being MPECed on 11 May 2022, has a perihelion at 1.1224 AU and a MOID of 0.2225 AU. There are no optical observations listed in the MPEC, so the absolute magnitude is very uncertain but listed as H = 18.8. It seems to be about 300 m in diameter.
  31. Comet C/2022 F2 (NEOWISE), a comet discovered in the far South by WISE just a few days after perihelion at 1.5861 AU. The inclination is 97.29 degrees so this is in a retrograde orbit. The period is about 143 years. It is faint at about 17th magnitude and unlikely to brighten dramatically.
  32. 2022 DG1, a few hundred meter-sized asteroid with perihelion at 0.8479 AU and an eccentricity of 0.7. The MOID is 0.1109 AU.
  33. 2010 KC138 = 2019 AG3, was first seen by WISE with 6 observations during a waxing crescent Moon on 18-19 May 2010, but this tracklet received no optical ground-based followup. It was seen again in 4 frames taken during one night in December 2018 by Pan-STARRS, and then seen by the Catalina Sky Survey in January 2019. The orbit is eccentric with eccentricity = 0.54 but only moderately inclined. The MOID is 0.0315 AU and the perihelion is at 0.7843 AU. With the known orbit, stacking WISE frames gave another detection in January 2010. This object appears to be about 127 meters in diameter with a low albedo.
  34. 2010 OZ100 = 2021 LT3, discovered by WISE in July 2010 but received no optical followup. Now identifed with 2021 LT3. MOID = 0.2234 AU, perihelion at 0.5442 AU, eccentricity = 0.77.
  35. 2010 GT21 = 2021 VE10, discovered by WISE in April 2010 but received no optical followup. Now identified with 2021 VE10. MOID = 0.1853 AU, perihelion at 1.1919 AU.
  36. 2010 CN233 = 2010 BO127 = 2010 BH149 = 2010 BF150, a consolidation of 4 WISE tracklets containing 52 observations from 29 Jan 2020 to 4 Feb 2010, giving an Earth-crossing NEO with a perihelion of 0.9029 AU and a MOID of 0.1350 AU. The eccentricity is high at 0.589. This received no optical followup in 2010 and has not been picked up in ground-based optical surveys. A fit to the 4-band IR data from 2010 suggests a size of 640 m but there seems to be a substantial lightcurve so this may be bigger than the spherical equivalent diameter.
  37. 2010 BV132 = 2021 MB2, a PHA with a MOID of 0.0236 AU and a perihelion at 1.0074 AU, was discovered by WISE in Jan 2010 with 12 observations over 2 days but received no optical followup. It was recovered by Pan-STARRS in 2021 and tracked for 4 days but that object has now been identified with the previous WISE tracklet.
  38. 2014 YF, discovered by Pan-STARRS in 2014, was recovered by WISE in early November 2021. This is an Aten with a period of 0.87 years.
  39. 2021 VB4, an eccentric, inclined PHA with a MOID of 0.02 AU and a perihelion at 0.9721 AU.
  40. 2010 KL66 = 2021 CD3, an object observed many times by WISE in May 2010 as 2010 KL66 but which received zero optical followup, has been linked with 2021 CD3. The MOID is 0.19 AU and the perihelion is at 1.1323 AU. A thermophysical fit to the 2010 and 2021 WISE data gives a diameter near 500 m with a high thermal inertia.
  41. 2021 TD32, an Earth and Mars crossing PHA with a MOID of 0.045 AU and perihelion at 0.9481 AU. Both the MOID and the H magnitude just barely qualify this object as a PHA. The eccentricity is 0.42 and the inclination is 25 degrees. Update 5/15/2023: recovered in 2023, now MOID is 0.0451 AU and the H mag is 21.89.
  42. 2021 NN50, just barely an NEO with perihelion at 1.2997 AU. This was seen by Pan-STARRS in July with a ~1 hour arc, and two more ~1 hour arcs in August. Then WISE got 7 observations on a 1 day arc in September, which led to followup observations and the MPC connected all the dots to get this MPEC.
  43. 2021 QA6, a highly eccentric PHA with perihelion at 0.9221 AU and aphelion at 5.1872 AU. The MOID is 0.0267 AU. The period is 5.34 years so it could have been visible 16 years ago. The diameter is several hundred meters.
  44. 2021 PN26, a highly eccentric Aten with a orbital period of 0.62 years, perihelion at 0.3073 AU, and a MOID of 0.0611 AU. The orbit predicts that there was a close pass in August 2016 but in the far southern sky. Currently the orbit uncertainty makes searching the NEOWISE archival data from 2016 rather difficult.
  45. 2021 PM3, an NEO with perihelion at 1.2583 AU and a MOID of 0.2445 AU, detected at 0.4 AU range.
  46. 2021 OC2, an object with a perihelion at 1.2954 AU which just barely qualifies as an NEO. The detection range was 0.8 AU but the H mag is 20.5, so this is rather dark and large.
  47. 2021 ND2, a fairly large NEO with a perihelion at 1.0965 AU and a MOID of 0.2579 AU. The period is 5.89 years and the eccentricity is 0.66 so its aphelion is past Jupiter.
  48. 2021 MP1, a large (probably bigger than 1 km) bright NEO found by WISE 8 days before the full Moon. The eccentricity is 0.52 and the inclination is 31 degrees, with perihelion at 1.22 AU.
  49. 2005 GH, a fairly eccentric and moderately inclined NEO recovered by WISE 16 years after its last observation. The position was ~30 degrees away from the prediction using the orbit from 2005. The period is 3.21 years so 5 orbits of the 2005 GH is pretty close to 16 years and it is once again in a favorable position for observation. This is probably fairly large (~400 m) with low albedo. The MOID is 0.2446 AU and the perihelion is 1.1364 AU.
  50. 2021 DG2, a fairly large NEO with perihelion at 1.2672 AU and a MOID of 0.2885 AU. Discovered when 1.1 AU from the Earth.
  51. 2021 CT5, several hundred meters or more in diameter, is an eccentric (e=0.55) and highly inclined (i=38.4 deg) NEO with perihelion at 1.1321 AU. Update 15-Apr-2021: WISE reobserved this object in April, and ground-based followup observations lengthened the arc, allowing a precovery by stacking WISE frames from October 2020. A thermophysical model gives a diameter just over 1 km.
  52. Comet C/2021 A10 (NEOWISE), a retrograde comet with inclination of 151.5 degrees and perihelion at 1.2685 AU. The period is about 840-900 years. This will probably remain faint.
  53. Comet P/2021 B3 (NEOWISE), a retrograde comet with 119.5 degrees inclination and perihelion at 2.16 AU. It will probably remain faint. It is currently in the far Southern skies but moving North.
  54. Comet P/2015 J3 = P/2021 B1 (NEOWISE), a periodic comet recovered in 2021. Perihelion at 1.49 AU. Inclination is 8 degrees. It will remain faint.
  55. 2015 OO = 2010 CR247, and 2010 CR247 was reported by WISE and received no followup. In 2015 Pan-STARRS picked up 2015 OO and now it has been connected to the WISE tracklet from 2010. MOID = 0.0331 AU and optically just too faint to be a PHA.
  56. 2019 YH4 = 2010 CP199, and 2010 CP199 was reported by WISE but not followed up. In 2019 Pan-STARRS picked up 2019 YH4 which has now been connected to the WISE tracklet. MOID = 0.3564 AU.
  57. Comet C/2021 A7 (NEOWISE), a faint parabolic comet with perihelion at 1.967 AU and 78 degree inclination. Several kilometers in size.
  58. Comet C/2021 A4 (NEOWISE), a faint comet with perihelion at 1.146 AU and 112 degree inclination. Probably over a kilometer in size. Period ~400 years.
  59. 2021 AF4, a fairly low albedo NEO with a perihelion at 0.49 AU and a MOID of 0.1514 AU. WISE detected it a range of 0.65 AU so it is probably about half a kilometer in diameter. The eccentricity is high at 0.8 and the inclination is 9 degrees. The optical recovery was about 2-3 magnitudes fainter than the prediction based on WISE data alone.
  60. Comet C/2021 A2 (NEOWISE), a retrograde comet (i = 107 degrees) with a perihelion at 1.41 AU. Discovered at ecliptic latitude -51 degrees.
  61. 2020 YG5, a several hundred meter diameter NEO with a MOID of 0.2547 AU and a perihelion at 0.7172 AU. The eccentricity is high at 0.7. Discovered by WISE at 61 deg ecliptic latitude moving toward the Sun on the sky.
  62. 2020 WU5, a large NEO with a MOID just outside the definition for a PHA at 0.0529 AU. The perihelion is at 0.9567 AU, and the period is 1.11 years. The inclination is fairly large at 43 degrees. It should be quite easy to see in early January 2021. The current orbit predicts that WISE should have seen it in February 2010, but the area of the error ellipse is bigger than the sky, so more observations are needed to allow precovery.
  63. 2020 WT5, an NEO with a MOID of 0.0185 AU that is just a bit too faint at H = 22.3 to be a PHA. The perihelion is at 0.9755 AU. It was detected by WISE at a range of 0.24 AU so it is probably larger than 140 m in diameter. Indeed, the JPL Horizons ephemeris service gives H = 21.965, just barely bright enough to be a PHA, while a thermophysical model of the IR data gives a best fit with a diameter of 241 m, and posterior median of 193 m with a 1 sigma range of 151 to 261.
  64. 2020 WR5, a fairly dark Earth and Mars crosser with perihelion at 0.7621 AU and a MOID of 0.2294 AU.
  65. 2020 WB5, a Mars crosser with a perihelion of 1.2214 AU and a MOID of 0.3059 AU. WISE detected it at a range of 0.7 AU, implying that it is fairly large and low albedo.
  66. 2020 WH2, a Mars crosser with a perihelion at 1.0399 AU and a MOID of 0.1815 AU.
  67. 2008 GQ3, recovered by WISE after more than 12 years with no observations. The position was many tens of degrees off the prediction from the old orbit, corresponding to about 61 days of motion in its 3.21 year orbit. The MOID is 0.1139 AU and the perihelion is at 1.0423 AU.
  68. 2020 VA, first seen by the Mt Lemmon Survey with 5 frames covering only a 1 hour arc, was recovered by WISE 13 days later during the full Moon. The 2020 VA designation indicates a discovery in early November based on two WISE tracklets which then were connected to the earlier "isolated tracklet" from Mt Lemmon. The MOID is 0.0921 AU and the perihelion is at 1.0806 AU.
  69. N00h5kn was observed by WISE in 9 frames spanning 14 hours on 17-18 Sep 2020. The angular rate was high at 6.1 arc-seconds/minute, and the RMS error of the best orbit fits was 0.67 arc-seconds. So it's a pretty solid detection, but no optical detections were obtained, so it goes out as "not confirmed". The perihelia of the orbit cloud fit to the data range are between 0.56 and 0.62 AU with a median of 0.59 AU, but the aphelia range from 2.1 to 22.5 AU. For the most likely orbit (NEOCPnomin) a = 5.8285 AU with e = 0.8976 although comet-like orbits with a ~200000 AU are also considered. The distance at the time of the WISE observations was 0.4553 AU for the nominal orbit, with a distance from the Sun of 1.1083 AU and a phase angle of 65 degrees. The infrared data give ~400 meter diameter for this orbit, and it would have had a visual magnitude of ~22.2 for an albedo of 0.03. The actual upper limit on the visual brightness is hard to determine from the data at the MPC. So N00h5kn is probably a real object with high quality IR data but also very dark so it was hard to find optically. The link above goes to the CNEOS Scout assessment of the impact hazard from this object, which is fortunately negligible.
  70. 2020 TS2, an asteroid with a perihelion at 0.1263 AU! The MOID is 0.2025 AU. This has a period of 3.95 years and will be easily observable from the Southern hemisphere for the next month. Further observations now will facilitate a precovery in WISE data from 2016.
  71. 2017 WC16, recovered by WISE with a 15 observation tracklet after 3 years of not being observed, has a perihelion at 1.1 AU and a period of 3.02 years. The position was 0.6 degrees away from the prediction based on the 2017 observations which covered a 9 day arc. This corresponds to a 1 day error in the period, which is now well known using a 3 year arc.
  72. 2020 SP4, a PHA with a MOID of 0.0235 AU and a perihelion at 0.9658 AU. The aphelion is out near Jupiter's orbit. This is probably low albedo.
  73. 2020 SE4, a Mars crosser with a MOID of 0.1832 AU and perihelion at 1.0503 AU. Seen by WISE 37 times over 5 days, but with no optical data so the albedo and optical brightness are unknown.
  74. 2020 RZ2, an Earth and Mars crosser,with perihelion at 0.82 AU and a MOID of 0.1318 AU.
  75. 2020 QZ6, a Mars crosser with a perihelion at 1.24 AU. See by WISE in 8 frames over 5-6 Sep 2020, reported on 9/7, then it was found on earlier frames taken a week earlier from Pan-STARRS and Mt Lemmon, so discovery credit will be assigned later when it is numbered.
  76. 2020 PR6, an Earth and Mars crosser, with perihelion at 0.9038 AU and a MOID of 0.1038 AU. About 400 meters in diameter.
  77. 2020 OT7, a small dark asteroid in a fairly eccentric orbit that sat on the NEOCP for 3 weeks before the Hawaii group picked it up at ~24th magnitude with the CFHT 3.6 meter. The MOID is 0.0558 AU and the perihelion is at 1.0392 AU.
  78. Comet C/2020 P1 (NEOWISE), discovered by WISE in the far Southern sky when still 1.7 AU from the Sun and 1.2 AU from the Earth. Parabolic orbit with a perihelion at 0.34 AU on 20 Oct 2020. Could get bright near perihelion.
  79. 2011 CN2, an Earth and Mars crosser recovered by WISE, with a MOID of 0.0516 AU. Discovered by Pan-STARRS in 2011, and not seen for 9 years. It was about 8 degrees off of the old prediction.
  80. 2020 KZ7, an Earth and Mars crosser with a MOID of 0.0837 AU and a perihelion at 0.9112 AU.
  81. 2020 MV, an optically faint Earth and Mars crosser with a MOID of 0.0534 AU and a perihelion of 0.9360 AU. This is probably bigger than 140 meters, given the range at detection, and very dark.
  82. 2020 LC2, a high eccentricity object (e = 0.65) that ranges from Jupiter's orbit to close to Earth's orbit. The MOID is 0.1525 AU and the perihelion is at 1.0626 AU.
  83. 2020 LC1, a large Aten with a period of 0.935 years and a perihelion at 0.6419 AU just inside the Venus orbit. The MOID is 0.1192 AU. A thermophysical model fit gives a diameter of about 566 meters with a 1 sigma range 476-720. At first seen only by WISE but with more than 15 observations covering a 13 day arc. Mt. John in New Zealand got optical data later. Update 9/30/2020: I found WISE observations from 2019 which serve to greatly reduce orbit uncertainties. These were so close to the celestial pole that the track appeared to be too curved in (RA,Dec) space, so it was not reported in 2019. Update 5/3/2023: 2020 LC1 and 2019 HF3 are the same object, with a MOID of 0.1187 AU and a perihelion at 0.6423 AU.
  84. 2006 CN10, an NEO recovered by WISE after 14 years of non-observation. The predicted position using the orbit from 2006 data was 3 degrees off. The MOID is 0.1044 AU and the perihelion is at 1.1002 AU.
  85. 2020 JU, an Aten with a period of 0.9 yrs, a perihelion at 0.8494 AU, and a MOID of 0.0019 AU. There are 14 observations from WISE spanning 2 days but no optical followup detections or reported attempts. The Moon is nearly full, the object is far South, and there is a pandemic going on.
  86. 2020 HV2, a several hundred meter diameter Earth-Mars crosser picked up by WISE at the North Ecliptic Pole, moving away from the Sun. The perihelion is at 0.74 AU, and the MOID is 0.24 AU.
  87. 2020 GX3, an object with 8 observations spanning 0.7 days from WISE but no optical followup detections although attempts were reported, with about a 70% chance of being an NEO and 24% chance of being a PHA based on the orbit cloud on the NEOCP. The nominal orbit on the NEOCP had inclination 24 degrees, eccentricity 0.9, and a=11.81 AU. Probably low albedo. Now listed at the MPC with no orbit. Given that 99% of asteroids are NOT NEOs, this is probably not an NEO based on Bayesian statistics.
  88. 2020 GW3, an object with 12 observations spanning 1.9 days from WISE but no optical followup detections although attempts were reported, with about a 54% chance of being an NEO and 46% chance of being a PHA based on the orbit cloud on the NEOCP. The nominal orbit on the NEOCP had inclination 1 degree, eccentricity 0.1, and a=1.07 AU Probably low albedo. Now listed at the MPC with no orbit, which is unusual for an object with a multi-day observational arc.
  89. Comet C/2020 F3 (NEOWISE), a small retrograde comet with a perihelion at 0.29 AU coming up on July 3, 2020. The period is about 1000 years. It was clearly active when detected by WISE. Update 7/9/2020 - this comet is visble as a naked-eye object! Brightest of all the many WISE and NEOWISE comets.
  90. 2020 BN11, a low albedo NEO with a perihelion at 0.84 AU, and a MOID of 0.0995 AU. WISE detected it at 0.3 AU range, indicating a few hundred meter diameter.
  91. 2020 BN10, a PHA and Aten with a MOID of 0.0464 AU and a period of 0.89 AU. The perihelion is at 0.6087 AU so this also crosses the Venus orbit. WISE picked up 2020 BN10 at ecliptic latitude -68 degrees.
  92. A/2020 A1, not an NEO because the perihelion is at 1.69 AU, but on a comet-like orbit with an inclination of 149.3 degrees. It is currently outbound from the Sun but still getting closer to the Earth until the end of January 2020.
  93. 2019 XV3 is another object with a low albedo. The median H in the NEOCP cloud got 2.5 magnitudes fainter when the optical confirmation data came in. The MOID is 0.2122 AU and the perihelion is 1.1556 AU.
  94. N00fry1 was not confirmed, even though linked PDF from CNEOS Scout gave it a 100 percent chance of being an NEO, and 78 percent chance of being a PHA. The inclination is probably over 90 degrees [and thus retrograde]. Confirmation was attempted at Mt Lemmon with a 1.5 meter telescope, but the current confirmation system does not make it easy to get upper limits on non-confirmed objects. Low albedo objects can easily be 2 magnitudes or more fainter than the estimates on the NEOCP. So this object is probably very dark, but will have to be recovered by chance at some later time.
  95. 2019 WV6, not an official NEO with perihelion at 1.3804 AU and a MOID of 0.3965 AU. It is a Mars crosser and can get close to Jupiter.
  96. 2019 WH1, an eccentric, moderately inclined NEO with a MOID of 0.2127 AU and a perihelion at 1.0519 AU.
  97. 2019 UT9, a large NEO with a fairly eccentric orbit [e = 0.64]. Given the range at WISE detection, it could be as large as a kilometer. The MOID is 0.1128 AU.
  98. 2019 RM4, definitely an NEO that received minimal followup and no MPEC. The nominal orbit from the NEOCP had a perihelion at 0.5299 AU, a period of 1.653 years, an inclination of 32 degrees, and a MOID of 0.2947 AU. This Daily Orbit Update lists this object as K19R04M and gives the orbit while this gives the observations. The orbit is very uncertain, with a 1 sigma range on the period of 1.25 to 5.3 years.
  99. 2019 NN7, observed by WISE very close to the South Ecliptic Pole and moving toward the Sun, and thus obviously an NEO, failed to get any confirmation observations so it limps into the catalog in this Daily Orbit Update. Look for K19N07N. MOID for this orbit is 0.18 AU. Probably dark but its discovery near the full Moon made ground-based recovery hard. The orbit is very uncertain except for the perihelion being about 0.79 AU. The one sigma range on orbital periods is between 2.5 and 47 years, so this one will have to be recovered by chance.
  100. 2019 OJ, a large (close to 1 km) asteroid with perihelion at 0.8 AU and aphelion at 5.2 AU, so crosses the orbits of Jupiter, Mars and Earth. The inclination is fairly high.
  101. 2014 MF18, an optically faint Aten with a very small MOID of 0.0074 AU. Recovered by WISE after not being observed for 5 years. Given the range when WISE detected it, the diameter is probably greater than 40 meters giving an albedo less than 4 percent.
  102. 2019 KG7, discovered by WISE at ecliptic latitude -82 degrees, is an Earth and Mars crosser with a MOID of 0.24 AU. The eccentricity is 0.68 which is fairly high and the inclination in 37 degrees which is a bit high for NEOs but not too unusual. Given the range at discovery, it is probably several hundred meters in diameter.
  103. Comet C/2019 L2 (NEOWISE), a retrograde comet with perihelion at 1.619 AU from the Sun. The period is about 119 years.
  104. 2019 KB2, a rare MPEC with only infrared observations from WISE, is probably over 500 meters in diameter with a perihelion at 1.1752 AU, and a MOID of 0.4654 AU. It was discovered at far Southern declinations.
  105. 2019 KC, an object probably larger than 140 meters given its 0.16 AU range at discovery, with a MOID of 0.0118 AU. However, its H magnitude is only 22.3 so it misses being a PHA.
  106. 2019 JR7, almost certainly larger than 140 meters given that WISE discovered it at 0.23 AU range, and with a MOID of 0.0123 AU, but with an H magnitude of 22.1 so it misses being a PHA.
  107. Comet C/2019 H1 (NEOWISE), a faint comet with perihelion at 1.845 AU and a binding energy z = 1/a of 0.00338+/-0.00062, so it seems bound by 5 sigma but the orbital period is very uncertain.
  108. 2019 HF3, found by WISE at far southern ecliptic latitude, has an orbit with perihelion at 0.6850 AU and a MOID of 0.0663 AU. Given the range at discovery, this is probably a large object with low albedo. Update 5/3/2023: 2020 LC1 and 2019 HF3 are the same object, with a MOID of 0.1187 AU and a perihelion at 0.6423 AU.
  109. 2019 HL, probably several hundred meters in diameter, with a perihelion at 1.1352 AU and a MOID of 0.2957 AU.
  110. 2019 DF2, observed 10 times by WISE but receiving no ground-based followup, is probably a very low albedo asteroid with a very uncertain orbit. Look for K19D02F on this orbit update. For what it's worth, the median MOID of the orbit cloud on the NEO Confirmation Page was 0.13 AU and the perihelion was 0.80 AU.
  111. 2019 DD2, a PHA with a MOID of 0.046 AU. WISE detected this nearly 0.4 AU from the Earth so this is probably a few hundred meters in diameter and quite dark.
  112. 2019 AN13, an NEO with perihelion at 1.1384 AU and a MOID of 0.2481 AU. WISE obtained 19 obervations over a two day arc, which then got connected to THREE "isolated tracklets" from Pan-STARRS in November, December and January.
  113. 2019 AH7, optically very faint with H=23.3, but probably a few hundred meters in diameter based on the distance at detection by WISE, so this object has very low albedo. The MOID in the MPEC is 0.0509 AU, so just outside the PHA definition, but the MOID on the Horizons page has been updated with new data, and is 0.4992 AU.
  114. 2018 YE2, a moderately inclined and eccentric Mars crosser with a MOID of 0.1346 AU. The perihelion is at 1.0771 AU. It was detected by WISE over 0.5 AU away indicating it is probably above 0.5 km in diameter with an albedo less than 9 percent.
  115. 2018 XY3, an eccentric and inclined PHA with a MOID of 0.0476 AU and a perihelion of 0.7984 AU. Quite dark and large.
  116. 2018 WE3, an eccentric PHA that ranges from 0.9 AU to 4.5 AU from the Sun, first seen by Pan-STARRS 2 in early July 2018 for 4 frames spanning 48 minutes, but lost without followup. WISE got 20 frames spanning 5 days in late November. Given the range when WISE saw it the object it probably 500 m or more with a quite low albedo. The MOID is 0.0238 AU. Update 12/11/18: thermophysical model gives a diameter between 450 and 506 m with an albedo of 2.8 percent.
  117. 2018 WD1, a very faint NEO with a MOID of 0.0273 AU. Discovered when very close to the Earth, this object is probably quite small - too faint to be a PHA.
  118. 2018 VQ9, almost a PHA with a MOID of 0.0513 AU. The orbit is quite eccentric, with aphelion out near 4.7 AU, so perturbations by Jupiter will be a factor. It was picked up at distance of more than 0.4 AU so it is probably bigger than 400 meters in diameter, and is likely to be a dark C type object, although the thermal modeling of the IR data is yet to be done.
  119. 2018 VL7, an NEO with a rather Earthlike orbit with perihelion at 0.8961 AU and a MOID of 0.1159 AU. The synodic period is 12.00 years, so this object is easily observable every 12 years.
  120. 2018 TO6, an Amor with perihelion at 1.184 AU and a MOID of 0.299 AU.
  121. 2018 RW27, just barely an NEO with perihelion at 1.2848 AU. The eccentricity is 0.53.
  122. 2018 RK4, not an NEO with a perihelion at 1.4268 AU, but a Mars crosser with an aphelion close to Jupiter's orbit.
  123. 2011 WM46, a large NEO with perihelion at 1.1341 AU, recovered by WISE after 7 years without observations. The best fit thermophysical model has D = 709 m with an albedo of 4.5%, but with only one NEOWISE epoch at a large phase angle this is quite uncertain.
  124. 2018 QT1, a high eccentricity Aten asteroid with a perihelion at 0.2682 AU, inside Mercury's orbit, and an aphelion at 1.0505 AU just outside the Earth's orbit. The MOID is 0.0334 AU, but the absolute magnitude in the MPEC is too faint for a PHA. The estimate of H as of 2 Sep 2018 on the JPL Horizons ephemeris service is brighter than 22, but the IR data suggest a median posterior diameter of 122 m, smaller than the 140 m cutoff for a PHA, but with a 1 sigma range of 96 to 159 m.
  125. 2001 PU9, recovered by WISE after 17 years. Perihelion at 1.1113 AU and a MOID of 0.1187 AU. Given its 1 AU distance at recovery, the diameter is probably close to 1 km with a low albedo. A thermophysical model based on the WISE IR data gives a diameter of 770+145-95 m, so not quite over a km.
  126. 2018 PF22, a very eccentric (e = 0.82) object with perihelion at 0.45 AU. Picked up by WISE at high ecliptic latitude.
  127. 2018 NT1, a Mars crosser with perihelion at 1.1049 AU and a MOID of 0.1202 AU.
  128. Comet C/2018 N1 (NEOWISE), with perihelion at 1.3079 AU to occur about 2 Aug 2018. The current orbit is parabolic.
  129. 2018 ML8, a fairly high eccentricity (e = 0.47) NEO with a perihelion at 1.12 AU and a MOID of 0.1055.
  130. 2018 MJ8, a high eccentricity (e = 0.54) Mars crosser but not an NEO, with perihelion at 1.38 AU.
  131. 2018 LK2 a PHA with a MOID of 0.0461 AU. This in probably a few hundred meters in diameter.
  132. 2018 KK2, a moderately eccentric object object that just makes it as an NEO with a perihelion at 1.2832 AU, and a MOID of 0.2849 AU. This is a fairly large object, close to a kilometer in size, since WISE picked it up at a range of 1.2 AU.
  133. 2018 JW1, a moderately eccentric object with perihelion at 0.91 AU and aphelion at 3.1 AU. The MOID is 0.0604 AU.
  134. 2018 HT3. This object spent 18 days on the NEOCP between its discovery by WISE and its follow-up by the CTIO 0.6 m astrograph. A combination of bright Moon and southern declinations impeded followup. Its orbit is very eccentric, crossing the orbits of Jupiter, Mars, Earth and Venus. It is also quite large: just under 1 km in diameter. The MOID is 0.3349 AU.
  135. 2018 GA, a moderately eccentric NEO with a perihelion at 0.99 AU, and an aphelion in the main belt. Discovered while the Moon was nearly full. The MOID is 0.1107AU.
  136. 2018 EC9, a faint NEO with a MOID of 0.0209 AU. The orbit has a perihelion of 1.0066 AU and an eccentricity of 0.48. This is probably rather dark, otherwise WISE would not have seen it at a range of 0.15 AU. Analysis of the IR data gives a median posterior of 6% for the albedo, and 84 meters for the diameter.
  137. 2018 EQ4, an Earth and Mars crossing asteroid with eccentricity of 0.57 and a MOID of 0.10 AU.
  138. 2018 EN4, not an NEO, but an object with a very comet-like orbit having an inclination of 82o, an eccentricity of 0.93, and a perihelion at 1.45 AU. No activity seen, so it has an asteroid name.
  139. 2018 EB, a PHA with a MOID of only 0.0082 AU. As of 07 Mar 2018 it is top of the chart at the JPL Sentry web site with the highest cumulative Palermo impact hazard and a 2.3 part per million chance of hitting the Earth in 2070-2117. More observations to refine the orbit are needed. Update 17 Mar 2018: more data has removed 2018 EB from the threat list.
  140. 2013 JN22, recovered by WISE 5 years after it was tracked for 4 days following discovery by Pan-STARRS in 2013. It has a very large eccentricity of 0.79 and a perihelion inside Mercury's aphelion.
  141. 2018 CQ1, a fairly eccentric object which crosses the orbits of Venus, Earth and Mars. The MOID is 0.2182 AU.
  142. 2018 AE3, a fairly eccentric NEO with a perihelion at 1.046 AU. The MOID is 0.0739 AU.
  143. 2017 YA7, an eccentric Earth and Mars crosser with a MOID of 0.1964 AU and a perihelion at 0.795 AU.
  144. 2017 YN3, an eccentric Mars crosser with perihelion at 1.0824 AU and a MOID of 0.1052 AU.
  145. 2017 VT14, a small Earth, Mars and Jupiter crosser with a very small MOID of 0.0034 AU. This is slightly too faint optically to be rated a PHA. As of 1-Dec-2017 it is ranked number 3 in terms of impact threat by Sentry.
  146. 2017 VH2, a Mars crosser with a perihelion at 1.2367 AU. The MOID is 0.3761 AU.
  147. 2017 VT, an Earth, Mars and Jupiter crosser that just missed being a PHA with a MOID of 0.0522 AU.
  148. 2017 UQ4, a faint eccentric NEO with a perihelion of 1.0224 AU and a MOID of 0.0647 AU.
  149. 2017 TV4, a large dark NEO dicovered by ATLAS but seen by WISE first. The WISE data are reported in this MPEC. Search for K17T04V. The IR radiometric diameter is 0.9 to 1.2 km.
  150. 2017 TQ3, a highly eccentric object with a MOID of 0.1881 AU. Its orbit crosses the Earth, Mars and Jupiter orbits.
  151. 2017 TR2, an Earth crosser that only got 5 positions from WISE with no optical followup. Search the MPEC for K17T02R.
  152. 2017 SH33, a nearly 1 km diameter NEO that only got 11 positions from WISE with no optical followup. Search the MPEC for K17S33H. There is a slight chance that 2017 SH33 could be perturbed onto a colliding orbit so it is number 7 on the list of potential impactors as of 30-Dec-2017.
  153. 2017 SY32, an eccentric PHA with a MOID of 0.0403 AU. Its orbit crosses the Venus, Earth and Mars orbits.
  154. 2017 SP16, a high eccentricity object with a perihelion at 1.32 AU.
  155. 2017 RN17, a very eccentric (e=0.77) object that crosses the orbits of Earth, Mars and Jupiter.
  156. 2017 QY35, not an NEO but a Mars crosser with perihelion at 1.47 AU. Pan-STARRS imaged this twice 32 minutes apart, but WISE picked it up 3 weeks later and got a 3.7 day arc.
  157. 2017 OY68, not an NEO, but an orbital period close to Jupiter's. Perihelion at 2.056 AU.
  158. 1998 SZ27, an Aten class PHA with a MOID of only 0.0078 AU. This object was unseen for 19 years before WISE picked it up.
  159. 2017 QP17, an eccentric, inclined object that crosses the orbits of Mars, Earth and Venus. The MOID is 0.3591 AU.
  160. 2017 OP68, an almost PHA with a MOID of 0.0511 AU. The perihelion is at 1.03 AU so not quite an Earth-crosser.
  161. 2017 OO1. This object buzzed by the Earth on 7/22/17 and wasn't discovered until a day later. WISE had seen it on 7/22, but it was moving too fast for the automated pipeline to connect the dots. This MPEC has the belated report of the WISE data. Based on the IR flux this object is between 22 and 30 meters in diameter.
  162. 2002 JS2, a very eccentric asteroid with e = 0.82, recovered by WISE after 15 years without observations.
  163. 2017 MD9, an Earth-crossing asteroid with high eccentricity and a MOID of 0.168 AU.
  164. 2017 LQ1, not an NEO, first seen by Pan-STARRS for a 40 minute arc in April, then again by Pan-STARRS for 40 minutes in May. These were finally connected by WISE observations in June and subsequent followup. This is a Mars crosser.
  165. 2017 LU, a rather bright PHA (H=18.5) with a MOID of 0.0374 AU. The perihelion is at 1.0522 AU, but the Earth is at aphelion leading to the lower MOID.
  166. 2017 KD35. The WISE observations were on the NEO Confirmation Page and got followed up, leading to a connection to one-night stands in April and early May. These arcs of less than 30 minutes had not been followed up, and now all are connected. But this Mars crosser is not an NEO, with perihelion at 1.517 AU.
  167. 2017 KO34, a Mars, Earth and Venus crosser with a MOID of 0.0996 AU.
  168. 2017 KO31, an optically faint Mars crosser with a low albedo and a MOID of 0.1647 AU. The diameter is about 167 meters.
  169. 2017 HW1 is larger than a kilometer. The perihelion is a 1.15 AU and the MOID is 0.1478 AU.
  170. 2017 FU158, a fairly bright NEO with perihelion at 1.2 AU that crosses the orbits of Mars and Jupiter. The MOID is 0.3 AU.
  171. 2017 FL127, a faint NEO with a MOID = 0.0398 AU. The perihelion is at 0.99 AU, just inside the Earth's orbit, and the aphelion is at 4 AU. WISE detected this object at 0.27 AU range, and a thermophysical model to the IR and optical data gives a diameter of 164 m ± 11% implying a low albedo around 7%.
  172. 2017 FP64, a highly eccentric (e = 0.6) Mars and Jupiter crosser with a MOID of 0.2915 AU.
  173. 2017 CM32, a PHA with a high eccentricity that crosses the orbits of Jupiter, Mars and Earth. The MOID is 0.0112 AU. WISE actually got four frames on this in October 2016, when it made a much closer pass bythe Earth, but WISE requires at least 5 detections before reporting an object to the MPC. Thermophysical analysis gives a 5 percent albedo so this PHA is pretty big, about 630 m.
  174. C/2017 C1 (NEOWISE), a parabolic comet with perihelion at 1.53 AU. The inclination is high so WISE picked this up near the ecliptic pole.
  175. 2017 BA30, a Mars crosser with a MOID of 0.1462AU. WISE got over 180 frames showing this object. A thermophysical analysis gives an albedo of 0.04 and a diameter of 400 m.
  176. 2016 YN13 = 2000 EC14, probably a very dark Mars crosser, with a perihelion at 1.23 AU and a MOID of 0.2558 AU. This was on the NEOCP for three weeks until additional NEOWISE observations led to an optical recovery by Dave Tholen, then to an identification with 2000 EC14.
  177. 2017 AQ20, a large NEO (diameter over 1 km) in a very eccentric (e = 0.85), highly inclined (i = 51o) orbit, with perihelion at 0.61 AU and aphelion at 7.6 AU. So it crosses the orbits of Venus, Earth, Mars and Jupiter. Discovered at an ecliptic latitude of 80o. The MOID is 0.3881 AU.
  178. 2017 AP20, a large NEO with an eccentricity of 0.76 and a perihelion at 0.69 AU. The MOID is 0.2246 AU.
  179. 2016 YF8, an Earth crosser with a MOID of 0.0678 AU. This was discovered by WISE very near the South Ecliptic Pole.
  180. 2016 XY23, a Mars crosser with a MOID of 0.2319 AU. The eccentricity is 0.57.
  181. 2016 WN55, probably an Aten with semi-major axis of 0.83 AU, was observed by WISE over a two day arc, but not followed up by any optical observer. So the orbit is listed as K16W55N in this Daily Orbit Update, and not as an MPEC. The orbit is very uncertain, but if the distance to the object at the time of observation Δ = 0.384 AU is correct, the size is about 250 m.
  182. 2016 WF9, a PHA with a MOID of 0.0292 AU. The perihelion is at 0.9942 AU, while the aphelion is at 6.8 AU. Update 2/22/17: perihelion at 0.9817 AU, aphelion at 4.760 AU, based on 134 day arc.
  183. 2016 VM6, an NEO with perihelion at 1.23 AU. The eccentricity is 0.5.
  184. 2016 WS1, not an NEO but an object with a rather cometary orbit, having semi-major axis a=13.3 AU, eccentricity e=0.873, and inclination i=53 degrees. It was 1.8 AU from the Sun on 15-Nov-2016 and outbound.
  185. 2016 VK6, an NEO with a MOID of 0.0493 AU, but an optical absolute magnitude H=23 which is too faint to count as a PHA. However, the range at which WISE detected this object suggests a diameter bigger than 150 m and then a low albedo.
  186. 2006 DC158, not an NEO or a WISE discovery, but rather a highly eccentric object recovered by WISE after nearly 11 years of non-observation. The period is 5.36 years, and the perihelion is 1.427 AU from the Sun.
  187. 2000 AC229, not an NEO or a WISE discovery, but rather a highly eccentric and highly inclined object that had not been observed for more than 16 years when WISE saw it.
  188. 2016 UA107, a Mars-Earth-Venus orbit crosser with perihelion at 0.61 AU and an eccentricity of 0.77. The MOID is 0.3275 AU.
  189. Comet C/2016 U1 (NEOWISE), a faint comet with perihelion at 0.319 AU. The predicted perihelion passage is 14 Jan 2017.
  190. 2016 TJ18, a PHA with a MOID of 0.0103 AU. The perihelion is just under 1 AU, and the aphelion at 3.8 AU.
  191. 2016 SH45, with a MOID of 0.2297 AU and a perihelion at 1.15 AU.
  192. 2016 SG45, with a MOID of 0.1809 AU and a perihelion at 1.16 AU.
  193. 2016 SA36, a medium-sized asteroid with perihelion at 1.476 AU, so not an NEO. But it is a Mars and Jupiter crosser, so it may turn out to be a comet or a dead comet nucleus.
  194. 2016 SG1, a large NEO that crosses the orbits of Mars, Earth and Venus. The MOID is 0.3720 AU. Given the distance from the Earth at the time of the WISE detection, this is probably larger than 1 km. According to NEODys this object has a small but non-zero chance of hitting the Earth, so more observations are warranted.
  195. 2016 QM11, a highly eccentric, medium inclination NEO that crosses the orbits of Earth, Mars and Jupiter. The MOID is 0.1066. WISE picked this up 1.15 AU from the Earth, and a thermophysical model of the IR flux says the diameter is 1.255+14%-4% km. Hence this is definitely one of the few NEOs bigger than 1 km that remained to be discovered. This was on the JPL list of possible impactors for a few hours, due to future encounters with Jupiter.
  196. 2016 QU1, a highly eccentric, medium inclination NEO that crosses the Mars, Earth, Venus and Mercury orbits. The MOID is 0.2510 AU. The current observational arc spans 5 days, and the object is approaching the Sun at 2 degrees/day, so further observations would be very useful.
  197. 2016 PG67, a Mars crosser with a MOID of 0.2383 AU.
  198. 2015 TF, look for K15T00F in this daily orbit update, discovered by PANSTARRS in 2015, was actually seen by WISE in 2010 with 6 observations covering 11 hours. An Earth, Mars and Venus crosser. The MOID is 0.0497 AU, but the absolute magnitude is too faint at H=22.2 so it is not classified as a PHA. Analysis of the IR data from WISE and NEOWISE-R says the diameter is 217 meters ± 11 percent.
  199. 2012 UR158, a PHA with a very high eccentricity (0.86) and a small MOID of 0.0034 AU, was recovered by WISE after a 3.5 year gap in observations.
  200. 2016 OY2, an Earth and Mars crosser with perihelion at 0.91 AU and a MOID of 0.067 AU. This was discovered by WISE far in the South at declination -74o.
  201. 2016 KL1, an Aten and PHA with a MOID of 0.0238 AU. This also crosses the Venus orbit.
  202. 2016 JU38, an Earth and Mars crosser with a high eccentricity and pretty high inclination. The MOID is 0.1208 AU.
  203. 2016 HN3, a PHA with a MOID of 0.0302. The perihelion is at 0.96 AU.
  204. 2016 GB241, buried in a Daily Orbit Update (look for K16GO1B), is a Mars and Jupiter crosser with an eccentricity of 0.63 and semi-major axis of 3.49 AU. Just barely an NEO with perihelion at 1.28 AU. Update: this objects is also 2010 KT128, which received no optical followup after it was discovered by WISE. Thermophysical analysis gives diameter of about 870 m and an albedo of about 5 percent.
  205. 2016 GU216, a bright Mars, Earth and Venus crosser with a large eccentricity of 0.72. The MOID is 0.2828 AU.
  206. 2016 FG15, a rather eccentric Apollo asteroid with a MOID of 0.2306 AU. The eccentricity is 0.71.
  207. 2016 FO12, an Apollo asteroid with a very low MOID of 0.0012 AU. The orbit has a low inclination but a high eccentricity. The IR data show that the diameter is around 200 meters, and later astrometry made 2016 FO12 a "virtual impactor", which meant that orbits consistent with the available data can hit the Earth. But the uncertainties were still large, so the chance of an impact was low. The current data predicts no impacts in the next century.
  208. 2016 DL , an Aten class PHA with a MOID of 0.0473 AU, and an eccentricity of 0.47. The perihleion is at 0.378 AU, slightly inside Mercury's orbit, while the aphelion is 1.051 AU. This object was previously reported by WISE and designated 2010 BY20 but it received no followup at that time. Thermophysical analysis gives a diameter of 166 m and an albedo of 18 percent.
  209. Comet C/2016 C2 (NEOWISE), a parabolic comet with perihelion at 1.57 AU coming up April 19. Update: 2016 March 2.
  210. 2016 BC14, an Aten type PHA with a MOID of 0.0112 AU. The period is 0.82 years.
  211. 2015 PP291, first seen by Pan-STARRS in August 2015, then by WISE January 2016. The eccentricity is high at 0.80, so the perihelion is well inside the orbit of Venus. The MOID is 0.1561 AU.
  212. Comet C/2016 B1 (NEOWISE), a parabolic comet with a perihelion distance of 4.2 AU.
  213. 2002 AO11, recovered by WISE after 14 years without observations, is an Aten asteroid with a MOID of 0.0027 AU. Too faint to be a PHA at H = 22.7 mag.
  214. 2016 AA10, a PHA with a MOID of 0.0432 AU. The eccentricity is high, it is an Earth and Mars crosser.
  215. 2016 AZ8, a PHA with a MOID of 0.0297 AU.
  216. 2015 YC18, an Earth and Mars crosser with a MOID of 0.0515 AU and perihelion at 0.9209 AU. The optical brightness is very low, with H=25.1 mag, so this object probably has a low albedo.
  217. Comet C/2015 YG1 (NEOWISE), a parabolic comet with a perihelion distance of 1.70 AU and an inclination of 52 degrees.
  218. 2015 SS20 = 2015 WL16. This is a very dark object with a MOID of 0.0292 AU. It was first seen by WISE on 23 Sep 2015, but nobody was able to get followup detections. Thus the object was designated 2015 SS20 with no orbit solution. So I searched the WISE frames that might have contained the object and I found several more frames with 3 sigma detections, and then with this longer arc Dave Tholen found the source as a very faint moving blip on MegaCam frames he had taken in October. Meanwhile a second short arc from WISE had been designated as 2015 WL16 with no orbit. But now they are all linked for this potentially hazardous asteroid with a very low albedo. A thermophysical analysis based on the two NEOWISE epochs gives a best fit diameter of 175 meters and albedo just under 5 percent.
  219. Comet C/2015 X8 (NEOWISE), a parabolic comet with a retrograde orbit (inclination 155 degrees). The perihelion distance is 1.21 AU.
  220. 2015 XY378, an Aten asteroid with a semi-major axis of 0.71 AU, just inside the Venus orbit. The eccentricity is large at 0.49, so this crosses the orbits of the Earth, Venus and Mercury. The Earth MOID is 0.1977 AU.
  221. 2015 WM16, an Earth and Mars crosser with a MOID of 0.0818 AU. The inclination and eccentricity are fairly high.
  222. 2015 XB130, a PHA seen in two frames by Pan-STARRS on 12/1, then 9 times by WISE on 12/3, and several other ground-based observatories. The MOID is 0.0415 AU.
  223. 2015 VZ145, seen twice by Pan-STARRS in October, then 6 times by WISE in November, has small MOID of 0.0143 AU. The inclination is low, and the eccentricity is high: 0.54. The perihelion is just inside 1 AU. The optical brightness is too low to count as a PHA.
  224. 2003 WG166, which was tracked for 4 weeks in 2003 but not seen since, was picked by WISE after 12 years. This object is almost resonant with Jupiter, but its high inclination and eccentricity reduce the perturbations on its orbit.
  225. 2015 VR2, a high eccentricity Mars crosser that gets out close to Jupiter's orbit.
  226. 2015 US81, just barely an NEO with perihelion at 1.285 AU.
  227. 2007 WE55, an NEO recovered by WISE after 7.5 years unseen.
  228. 2015 TW346, an object with a fairly high eccentricity of e = 0.6, and a MOID of 0.3853 AU.
  229. 2015 TK237, with a MOID of 0.0358, just missing being a PHA because its H absolute magnitude is 22.3. My best fit to the optical H magnitude and the WISE IR data gives a low albedo and a diameter well above the 140 meter theshold for PHA, but the uncertainties are big enough to allow pretty good fits with diameters below the threshold.
  230. 2015 SF20, an Earth and Mars crosser with a MOID of 0.0553 AU, just misses being a PHA.
  231. 2010 UB8, an asteroid discovered by WISE in 2010, has been recovered by WISE in 2015 after a 5 year gap with no observations. The error in the predicted position at recovery was 5 degrees.
  232. 2015 RR150, a PHA with moderately high inclination and eccentricity. The MOID is 0.0240 AU.
  233. 2015 RS83, a very high eccentricity (e=0.75) Earth crosser with MOID = 0.1533 AU.
  234. 2015 RA36, a PHA with a MOID of 0.0468. The orbit is fairly eccentric and inclined.
  235. 2006 UR127, recovered by WISE after 9 years, MOID = 0.1865 AU.
  236. 2011 HJ61, recovered by WISE after 4 years, MOID = 0.1226 AU.
  237. 2015 QM3 is a fairly large Aten class asteroid whose orbit crosses the orbital radii of Mercury, Venus and the Earth. The MOID is 0.0610 AU.
  238. 2015 OS35, a fairly eccentric Mars crosser with a perihelion at 1.07 AU. The MOID is 0.2541 AU.
  239. 2015 OA22 is an eccentric, high inclination object with a perihelion just outside the Earth's orbit and an aphelion beyond Jupiter's orbit. The MOID is 0.0670.
  240. 2015 MQ130 is a Mars crosser with a perihelion just outside the Earth's orbit. But the MOID is 0.2687 AU.
  241. 2015 GN50. It must be spring cleaning day on the NEO confirmation page, because this MPEC is titled "46 New NEOs". 2015 GN50 was only observed by WISE with a total span of 0.5 days. The MOID is 0.0554 AU.
  242. 2015 JF11 is another of the 46 new NEOs. Only observed by WISE over a 1.25 day arc, its MOID is 0.0337 AU and it is listed as a PHA in the MPC database.
  243. 2015 KL157, a PHA with a MOID of 0.0091 AU. Based on the IR data, this object is dark and nearly 1 km in diameter.
  244. 2015 HA182, discovered 21 Apr 2015 by WISE, with ground-based followup giving a 10 day arc. Update 11 Jun 2015: 2009 HE = 2015 HA182, with a 1.48 year period. So WISE recovered this object 6 years after the last previous observation. MOID = 0.0713 AU.
  245. 2015 KH157, a PHA with a MOID of 0.0154 AU.
  246. Comet 141P/Machholz, a periodic comet with a 5.25 year period, discovered in 1994 but last observed in 2005, was recovered by WISE with 28 observations.
  247. Comet P/2015 J3 (NEOWISE), a periodic comet with a 6.36 year period, e = 0.56, i = 8.1 degrees.
  248. 2015 GK50, with a high eccentricity object swinging from almost Jupiter's orbit with aphelion at 5.1 AU to nearly the Earth's orbit with perihelion at 1.03 AU. The MOID is 0.2368 AU.
  249. 2015 GJ46, an object with a rather eccentric orbit (e = 0.77) that crosses the orbits of Mars, Earth and Venus. The MOID is 0.236 AU.
  250. 2015 FT344, a Mars crosser with a MOID of 0.2020 AU.
  251. 2015 FD341, a large Mars, Earth, Venus and Mercury crosser with a MOID of 0.1241 AU. It has a period less than 1 year, so it is an Aten class NEO. Update 3/20/15: A precovery by NEOWISE in 2014 which I found while searching for data to do a thermal fit then allowed a 1 hour arc from Siding Springs in 2013 to be added. Now a 3 opposition object with a 2 year arc. The best fit is a diameter of 900 m and an albedo of 0.15, but the Monte Carlo says the mean over all likelihood weighted distributions of poorly determined parameters is 750+/-130 m diameter.
  252. Comet 2015 G1, picked up by WISE on April 5, turns out to be Comet P/2008 S1 (Catalina-McNaught). Perihelion distance is 1.19 AU, and the period is between 6.74 and 6.76 years.
  253. 2015 FU332, a big, optically bright Mars, Earth and Venus crosser with a MOID of 0.2703 AU. The eccentricity and inclination are high. WISE discovered this at ecliptic latitude 67 degrees.
  254. 2015 FE120, a PHA with a MOID of 0.0116 AU.
  255. 2015 FY117, a Mars crosser with a MOID of 0.1494 AU.
  256. 2015 DX198, a Mars crosser with a perihelion at 1.024 AU and a MOID of 0.074 AU.
  257. 2015 BS514: Pan-STARRS picked this one up before WISE scanned over it. It is a Mars crosser with a perihelion at 1.3283 AU.
  258. 2015 BV512, a Mars and Jupiter crosser with a perihelion at 1.3337 AU.
  259. 2015 AK280, a high eccentricity (e = 0.7) PHA with a MOID of 0.0494 AU.
  260. 2002 GP186, recovered not discovered by WISE, 13 years after the first observations. It is an Earth crosser with a MOID of 0.0809 AU. The position based on the 2002 observations was off by 25 degrees.
  261. 2015 AY245, a PHA with MOID = 0.0190. Perihelion is at 1.003 AU.
  262. 2015 AC17, Mars crosser with MOID = 0.2409.
  263. 2014 YR43, a high eccentricity Earth and Mars crosser with MOID=0.31 AU. The eccentricity is 0.62.
  264. 2014 YS14, an Earth crossing NEO with a perihelion distance of 0.837 AU, and an eccentricity of 0.657. No MPEC was issued although one was warranted. Update 16-Jan-2015: Dave Tholen reobserved this object giving a 23 day arc, and gets orbital elements with argument of perihelion = 13.89320, semi-major axis = 2.4636696, longitude of ascending node = 124.56343, eccentricity = 0.6603313, inclination = 18.28931, and mean anomaly = 345.01793 at JD=2457000.5.
  265. 2014 YJ14, a large NEO with high eccentricity, e = 0.82. The perihelion is at 0.4 AU. The MOID is 0.1096 AU.
  266. 2014 XX31, a large bright NEO with a high eccentricity of 0.87. Its perihelion is inside Mercury's orbit, while its aphelion is outside Jupiter's orbit. The MOID is 0.4726 AU. This is the 51st WISE-related MPEC in the year since NEOWISE-R restarted the survey.
  267. 2014 XX7, a Mars crosser with MOID = 0.1645 AU.
  268. 2014 XQ7, a Mars, Earth and Venus crosser with a MOID of 0.3113. The eccentricity of e = 0.75 is quite high.
  269. 2014 VP35, with perihelion at 0.9552 and a MOID of 0.0262, is a bit too faint optically with H=22.6 to qualify as a PHA.
  270. 2014 UH210, an eccentric Earth & Mars crosser with a MOID = 0.0987 AU. Perihelion is at 0.8858 AU, aphelion at 4.2392 AU.
  271. 2014 UF206, largish Mars crosser with MOID = 0.1315 AU.
  272. 2014 UG176, and Earth and Mars crosser with a MOID of 0.1611 AU.
  273. 2014 TJ64, Mars crosser with MOID = 0.1537 AU.
  274. 2014 TF64, Earth and Mars crosser with MOID = 0.131 AU. Hign inclination = 53o.
  275. 2014 TW57, a Venus, Earth and Mars crosser with a MOID = 0.0569 AU. The semi-major axis is 2.02 and the eccentricity is 0.72.
  276. 2014 SR339, Mars crosser with perihelion at 1.15 AU, 15 observations by NEOWISE spanning 5 days plus 9 ground-based followup observations. This is appears to be close to a kilometer in diameter or bigger. Update: 11 Nov 2014: new orbit solution gives a = 1.2989, e = 0.3037, i = 29.790. So now an Earth and Mars crosser with a MOID of 0.036 and big enough to be a PHA.
  277. 2014 RH12, with a high eccentricity of 0.53, a perihelion at q = 1.01 AU, and a MOID of 0.0451 AU. Discovered by WISE at short range, Δ = 0.1 AU. The absolute magnitude is H = 22.83 which is too faint to qualify as a PHA, and the IR flux implies a small diameter, D = 71 ± 9 meters.
  278. 2014 QH433, a Mars crosser with a = 3.17, e = 0.56. The perihelion is at 1.40 AU so not an NEO.
  279. 2014 QK433, Mars crosser with a = 2.96, e = 0.60. The perihelion is at 1.19 AU, and the MOID is 0.1790 AU.
  280. 2007 RU10, recovered by WISE 7 years after it was last seen in 2007. A high eccentricity Mars and Earth crosser with a MOID = 0.0970.
  281. 2014 PP69, an object in a comet-like orbit with a = 12.6, e = 0.901, and inclination i = 93o, but no activity has been seen so it gets an asteroidal designation. MOID = 0.4354.
  282. 2014 PF68, a Mars crosser with a high eccentricity of e = 0.602. MOID = 0.1781.
  283. 2014 PC68, a Mars crosser with a MOID of 0.1047.
  284. 2010 ST16 = 2014 OT392. This object was recovered by WISE as 2014 OT392 but its orbit agrees with 2010 ST16. A high eccentricity NEO with MOID = 0.0961 AU.
  285. 2014 OR2, an asteroid in a comet-like orbit with a = 4.57 AU, e = 0.59, and inclination = 12o.
  286. 2014 OZ1, a Mars crosser with a MOID of 0.1982 AU.
  287. 2014 OY1, PHA with MOID = 0.0426 AU. Earth crosser with high eccentricity: e = 0.625.
  288. 2014 NM64, which fails to be a PHA due to its very low albedo leading to a faint optical appearance. MOID = 0.0489 AU, a = 2.84 AU, e = 0.626 and inclination 28.8o. 24 observations by WISE over 5 days. The Horizons database at JPL gives a brighter magnitude, H = 21.4 instead of 22.6, and thermal analysis of the WISE data says the diameter is about 200 meters.
  289. 2014 NE64, Mars crosser with semi-major axis a = 2.12 AU and e = 0.433. Probably big and dark since WISE picked it up at a range of 1.5 AU. Update 29-Jun-2017: recovered by WISE on 27-Jun-2017.
  290. 2014 NC64, Earth and Mars crosser with eccentricity e = 0.634. The MOID is 0.1972 AU.
  291. Comet C/2014 N3 (NEOWISE), a parabolic comet with perihelion at 3.846 AU, and an inclination of 61.7o. Discovered by NEOWISE on the 4th of July.
  292. 2014 NF3, an Venus, Earth and Mars crosser with MOID = 0.2146 AU.
  293. 2014 MK60, a PHA with a MOID = 0.0185 AU. This is an Aten with a period of 0.89 years.
  294. 2014 MQ18, very large NEO with a MOID of 0.2020 AU, discovered at 1.6 AU range. Eccentricity = 0.616, period = 5.3 years.
  295. Comet P/2014 L2 (NEOWISE), a comet discovered near perihelion at 2.1 AU from the Sun. Update 7-Jul-2014: this MPEC lists 4 different orbits which is a bit unusual. The best estimates give a = 6.26 to 6.28 AU, and eccentricity e = 0.6445, with perihelion at 2.23 AU.
  296. 2014 LQ25, appears to be a large (1 km) object with a very low albedo. It has a semi-major axis of a = 2.11 AU, an eccentricity of 0.69 and an inclination of 34 degrees, so it is a Mars, Earth and Venus orbit crosser. The MOID is 0.0909 AU.
  297. 2014 KG2, an object with a comet-like orbit, e = 0.78, a = 6.40.
  298. 2014 JN57, a PHA with a MOID of 0.0481 AU. Update: reobserved by Dave Tholen 21-23 Jan 2015, and the MOID has changed to 0.0514 AU.
  299. 2014 JH57, a very large NEO with a very eccentric orbit, e = 0.87. The perihelion is at q = 0.36 AU, so it crosses the orbits of all the inner planets.
  300. 2014 JL25, with a perihelion at 0.9967 and a MOID of 0.0135 AU, is a bit too faint to qualify as a PHA. However, the optical magnitudes are quite faint, so this probably darker and larger than the standard analysis suggests.
  301. 2014 HJ129, Mars crosser, MOID = 0.1700 AU. Probably pretty dark since the reflected optical light is faint. Update 5 Aug 2014: this has now been identified with 2010 AQ81, another WISE NEO. The orbit is now very well known, with MOID = 0.2117 AU.
  302. 2014 HQ124, an Earth and Venus crossing Aten with period = 0.79 years, and a PHA with MOID = 0.0083 AU. It will get as close as 3.2 lunar distances from the Earth on 8 June 2014.
  303. 2014 EQ49, a PHA with MOID = 0.0438. Probably dark with a diameter of a few hundred meters. Update 27-Jan-2019: WISE recovered this object, and the new improved orbit has a MOID of 0.0268.
  304. 2014 EN45, high eccentricity (e = 0.57) Mars crosser. Earth MOID = 0.1560. Could be very dark.
  305. 2014 ED, high eccentricity (e = 0.64) Mars, Earth and Venus crosser, MOID = 0.37 AU.
  306. COMET C/2014 C3 (NEOWISE). Parabolic retrograde comet with perihelion at 1.87 AU.
  307. 2014 CF14 is an Earth and Mars crosser, bigger than 1 km. Luckily the MOID is 0.1516 AU.
  308. 2014 CY4, a PHA with a MOID of 0.0399, and e = 0.84. This one has a fairly large relative velocity when close to the Earth, and looks to be quite dark, increasing the hazard it presents.
  309. 2014 BF63 is an object with a comet-like orbit, a = 5.17 and e = 0.67.
  310. 2014 BE63 is a Mars and Earth crosser with an eccentricity of 0.64, and a MOID of 0.1328. Ground-based followup with the Cerro Tololo 4 meter at magnitude 23.7!
  311. 2014 BG60 is a Mars and Jupiter crosser. The WISE estimated optical magnitude is much brighter than the reported optical magnitudes so this probably has a low albedo.
  312. 2009 UX17 was recovered by WISE on 18-19 Jan 2014. WISE also observed this source 16 Feb to 5 Mar 2010. This should be an interesting case for thermal modeling with multiple infrared apparitions. But it is not an Earth crosser and has a MOID of 0.1485 AU, so it is not currently a threat.
  313. 2014 AA53, Earth crosser with a MOID of 0.1402.
  314. 2014 AZ52, comet-like orbit with a perihelion at 1.48 AU.
  315. 2014 AQ46, a Mars crosser with a MOID of 0.2039. This object loitered at 92 degrees elongation for several days, so WISE got a 5 day arc by itself.
  316. 2013 YP139, a PHA with a MOID of 0.0033 AU. The velocity relative to the Earth at the MOID is 16 km/sec. This object is big and dark emitting lots of IR. WISE is back in business finding NEOs.
  317. 2011 BN59, an NEO with a comet-like orbit, a=4 AU, e=0.7. This was found in the last batch of tracklets from NEOWISE.
  318. 2011 BY24, an Earth crosser with a MOID = 0.0171 that probably should be a PHA because the IR estimated magnitude is 1.3 mags brighter than the optical magnitude, indicating a diameter bigger than the PHA threshold but with a low albedo.
  319. 2011 AH37, an Earth crossing PHA with MOID = 0.0348
  320. 2011 AT4, with perihelion distance = 1.42 AU, so it is only nearly an NEO
  321. 2010 YD3, probably a big dark NEO since optical followup failed, 40 WISE observations spanning 6.5 days. Update: 110 observations by WISE from 28 Nov 2010 to 26 Jan 2011, and observed by CTIO in the optical in April 2011. A rotating, cratered thermophysical model gives a 500-1500 meter diameter. MOID = 0.196.
  322. 2007 TR65, WISE recovered this Mars, Earth and Venus crosser last seen in Nov 2007
  323. 2010 YC1, a darkish Earth crosser, MOID = 0.1644
  324. 2010 XY82, an NEO with perihelion distance of 1.13 AU, but no MPEC was issued. Update 29 Jul 2013: recovered by Dave Tholen, MOID = 0.2943.
  325. 2010 XP69, a darkish PHA, MOID=0.0127
  326. 2010 XZ67, MOID=0.0648
  327. 2010 WE9, MOID=0.2479

Notes:
MOID is the Minimum Orbit Intersection Distance
PHA is a Potentially Hazardous Asteroid, with MOID < 0.05 AU
and absolute magnitude brighter than 22.
AU is astronomical unit, 149.6 million km or 93 million miles
i is the inclination
Apollo asteroids have a > 1 AU but perihelion at < 1.017 AU so they are mainly outside the Earth's orbit
Aten asteroids have a < 1 AU but aphelion at > 0.983 AU so they are mainly interior to the Earth's orbit

JPL's NEO office maintains a list of WISE discoveries, and the MPC maintains a breakdown of NEO discoveries by type and discoverer. WISE found about 20-30 percent of the NEOs discovered in 2010.
