This Week's Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Calibrations for March will include two monthly SRCA Full Radiometrics (DOY 062 & 090), one SRCA Full Spatial (DOY 076), and one screened SDSM (DOY 076).

Maneuvers:

2009/057 19:20:21 Resumption of pointing accuracy

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.

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.
