Maneuvers:
The next Lunar Roll Calibration is planned for DOY 2003/258 (September 15, 2003). Data collect between 13:13:22-13:19:52 GMT. The requested roll angle is -8.9233 degrees.
The next Terra inclination maneuvers are expected in October of 2004.
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.
