Maneuvers:
The next Terra MODIS Lunar Calibration Roll will be on DOY 2005/206 (July 25, 2005). The roll angle will be –7.2364 degrees. Data collect will be from 08:03:51- 08:10:21.
MODIS Anomalies:
Recently, MCST has seen higher than usual lamp currents in the 20W and 30W lamp configurations. In light of the recent events with the FM1 SRCA, it has been decided that future SRCA Full Spatial and Full Spectral calibrations will be performed using constant current mode instead of radiance mode. SRCA Full Radiometric calibrations will be performed as normal.
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.
