Maneuvers:

Again, there will be no MODIS roll maneuver in May because the roll angle would have been too great. The next attempt for a roll maneuver will be June. There is a Drag makeup maneuver being planned tentatively for May 8.

MODIS Anomalies:

None.

General Instrument Comments:

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

MODIS Telemetry Trends:

Nothing new to report.

Non-MODIS Significant Events:

None.
