Animated DIRBE Weekly 100 Micron Maps

The Figure below shows the 100 micron weekly maps from DIRBE as an animated GIF file.


The solar avoidance hole starts out in the Galactic center region (Dec 89) and then moves around the sky for 41 weeks. During two weeks of the mission JFET off tests were done to assess the affect of the warm transistors in the preamps on the 140 and 240 micron channels.

From the time variation of the intensity at a given point on the sky, it is possible to estimate the zodiacal intensity without prejudging the cosmic or galactic backgrounds.
