Maneuvers:
There was a Terra Inclination Manuever #23 on DOY 280 (10/7/09). The slew out start time was 280/15:34:49 and the slew back end time was 280/16:05:49. The maximum commanded yaw angle was -89.9082 degrees.
Loss of pointing accuracy times were 280/14:33:00 - 280/17:20:33.
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.
