Update from the SOCC SATOPS Morning Report April 12, 2002:
"On Wednesday, April 10 at ~19:30z, the NOAA-15 AMSU-A1 channel 11 signal
dropped dramatically. In the hours preceding the anomaly, channel 11 behaved
normally, its value varying periodically with orbital position between
~18600 and 18000 counts. At ~17:50z the pattern changed and by 18:45z it
began to drop steadily. Finally at ~19:30z channel 11 dropped instantly from
16500 to 7195 counts. Since then it has been steady between 7196 and 7194
counts. So far the engineering investigation has not revealed any other
abnormalities in AMSU data or spacecraft data that coincide with this
anomaly, but they are continuing to look into the matter."
