Maneuvers:

The next MODIS lunar calibration will be on August 16, 2003 (DOY 2003/228). Data collection will be from 19:24:54 -19:31:24 GMT, and the roll angle will be -5.1828 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.
