Maneuvers:
The January Lunar Calibration Roll will be on day 2005/030 (January 30, 2005). Data collect will be from 09:43:03-09:49:33 GMT with a roll angle of –4.6573 degrees.
MODIS Anomalies:
None
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody maintained at 290K and the Solar Diffuser Door at the Screened position.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
Non-MODIS Significant Events:
On day 2004/359/135215, the SFE-A HPM2 card experienced an SEU or SEL type event, which tripped TMON 16, turning off SFE-A at 135244. Science Record was disabled manually at 182510. At 203835, the FOT turned on SFE-A and re-enabled science record. Therefore, MODIS contains a data gap from 359/135244 to 359/203835.
