This update was posted on Tuesday, October 28, day 65 of the mission. The 60-day In-Orbit Checkout (IOC) period has formally ended and SIRTF has entered a 30-day Science Verification (SV) period. IOC was intended to demonstrate the functional performance of the observatory, while SV is devoted primarily to characterization of the science observing modes. At the moment, SV activities have been placed on hold, due to the enhanced solar activity.
