Maneuvers:
The next Terra MODIS Lunar Calibration Roll will be on DOY 2005/235 (August 23, 2005). The roll angle will be -6.8086 degrees. Data collect will be from 17:40:02 - 17:46:32 .
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.
