Maneuvers:

The next MODIS Lunar Roll Calibration is scheduled for August 9, 2001 ( DOY 221 ) from 05:24:35 to 05:31:05. A second lunar calibration will be performed without a roll maneuver on the same day from 20:23:37 to 20:30:07. During the second roll, the SMIR Itwk/Vdet will be temporarily set to 79/110.

MODIS Anomalies:

The MODIS PS2 Shutdown Anomaly report was presented on Monday, July 30, 2001.

General Instrument Comments:

MODIS is in Science Mode on the A-side with the SVD and NAD open, operating with the Formatter Resolution Flight Software Patches (FRFSP).

MODIS Telemetry Trends:

Trending has resumed with the instrument on the A-side. All appears nominal at this time.

Non-MODIS Significant Events:

None.
