MODIS Anomalies:
2008/252 Terra SFE-A Anomaly
Data loss: 2008-252-14:31:50.990824 - 2008-252-20:41:36.165791
Length of data loss: 06:09:46
2008/254 Terra Data Loss
Data loss: 2008-254-13:49:14 - 2008-254-13:51:09
Length of data loss: 00:01:55
Data loss occurred due to loss of K-band service on TDW that was accompanied by an operator error in executing contingency procedures.
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody maintained at 290K and the Solar Diffuser Door at the Screened position.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
