Maneuvers:

The next MODIS Lunar Roll Calibration is scheduled for 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.
