This Week's Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Calibrations for January will include two biweekly SDSM, one monthly Lunar Calibration Roll, one monthly SRCA Full Radiometric, one quad-monthly SRCA Full Spectral, and one quarterly PV Ecal.

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:

The next Terra MODIS Lunar Calibration Roll will be on DOY 2007/038 (February 7, 2007). The roll angle will be -11.2452 degrees. Data collect will be from 02:53:57-03:00:27.

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.
