April calibrations for the FM1 MODIS instrument include an SRCA full radiometric, an SRCA spectral, a PV Ecal, a Lunar Calibration Roll, and weekly SD calibrations.

Maneuvers:

The next FM1 MODIS Lunar Calibration via Spacecraft Roll Maneuver is April 12, 2003 (DOY 2003/102) with data collection from 20:23:18 to 20:29:58 GMT and a roll angle of -10.4528 degrees.

The Deep Space Calibration pitch maneuver(s) are still postponed pending the results of the Terra Deep Space Calibration maneuvers currently planned for March 26 and April 14, 2003.

MODIS Anomalies:

Recent SRCA calibrations have shown that SRCA lamp #2 is not producing the same output characteristics as the other SRCA 10 Watt lamps. Upcoming SRCA Full Radiometric and Full Spatial calibrations will use the backup lamp (#4) in lieu of lamp #2. After the data are analyzed, a decision will be made regarding which 10W lamps to use for the nominal schedule of SRCA calibrations.

Work is still underway to fix the current BST patch as well as modify the final BST patch that was nearing final review approval. This fix will solve the problem of MODIS Ground Command transactions being disabled by MODIS Stored Commands. A test review for the second BST patch has been scheduled for Wednesday, April 9th, 2003.

General Instrument Comments:

FM1 MODIS is in Science Mode. The SVD and NAD are Open, the survival heaters are enabled, and the Black Body is heated to 285 K.

MODIS Telemetry Trends:

The FM1 MODIS instrument telemetry is trending nominally and the radiative cooler temperatures have stabilized.
