lukewarm WISE still finding NEOs
The Wide-field Infrared Survey Explorer (WISE) has run out of hydrogen in its secondary tank. This is the big one that kept the telescope cold. Now the telescope has warmed up to 45 K, and telescope emission has saturated the 22 micron band. But the 12 micron band is still working for now since the small primary hydrogen tank is still keeping the detectors cold. And the 3.4 and 4.6 micron bands are working as well as ever. The IAU Minor Planet Center just published electronic circulars announcing the discovery of two Near Earth Asteroids by WISE, 2010 QD2 and 2010 QE2. Based on optical brightness, both are a kilometer or more in diameter. The WISE data will be used to make more accurate diameter estimates later.
