Maneuvers:

None

MODIS Anomalies:

MODIS data loss: 2009/078 15:45:02-15:45:10 Loss was due to operator error - flight controllers did not execute appropriate playback procedure to prevent data loss.

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.

After some deliberation it has been decided that Terra will now perform screened SDSM calibrations on a triweekly rather than a biweekly basis. The next screened SDSM calibration will take place on DOY 076.

MODIS Telemetry Trends:

Nominal telemetry trending is ongoing.
