Maneuvers:

None

MODIS Anomalies:

The Terra Science Formatter Equipment (SFE) spontaneously powered itself down on DOY 355, preventing science data recording and direct broadcast. The Terra FOT reactivated the SFE on DOY 357 and enabled science data flow on the following day. The nighttime day mode observation data from DOY 355 was lost as a result of this anomaly; the calibration has been rescheduled for 2009/005. Data loss times: 355/04:48:48 - 358/16:10:47

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.
