This Week's Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

During the upcoming week, it is planned to collect an extra 20 minutes of DAY rate data while the spacecraft is over the night side of the Earth. Solar Diffuser calibrations will likely occur on Wednesday, although the precise times have not yet been determined.

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.

MODIS Anomalies:

Investigation into the PS2 shutdown anomaly is still underway. An anomaly report is expected by the end of this month.

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.
