This paper describes the first result from Spitzer Observing Program GO-20101 , the goal of which is to explore the differences in brightness between the day sides and night sides of extrasolar planets orbiting the stars nearest the sun. This builds on the earlier spectacular Spitzer results (see here and here ) featuring direct detections of extrasolar planet light by measuring secondary eclipses. However, there are some important differences.
