This Week's Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Calibrations for February will include two biweekly SDSM, one monthly Lunar Calibration Roll, one monthly SRCA Full Radiometric, and one trimonthly SRCA Full Spatial.

Maneuvers:

There will be no Terra MODIS Lunar Calibration Roll in March, 2007. The required roll angle (-22.6381 degrees) exceeds the 20 degree magnitude limit.

MODIS Anomalies:

None

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.

Non-MODIS Significant Events:

Terra experienced a data loss due to a TDW/TD-6 spacecraft emergency. The data loss times for unrecoverable MODIS data loss are: 2007/032 19:43:13-20:46:27 GMT.
