Maneuvers:

The next Lunar Roll Calibration is planned for DOY 2003/288 (October 15, 2003). The data collect will occur between 08:35:34 and 08:42:04 GMT with a spacecraft roll angle of -13.16 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.
