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.
