In addition:
Electronics calibrations (PV & PC) will be scheduled for the week of the 16th.
A new set of SRCA cross-talk measurements are being planned for later this month and will use memory load patches to change the size of the SRCA sector from 10 frames to 55 frames in the same manner as was done on March 2, 2001.
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.
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.
