Maneuvers:
Terra Lunar Roll Calibration #74 will be performed on Tuesday, October 30, 2007 (DOY 2007/303). The slew times are from 03:09:33- 03:28:51 with a 90 minute buffer before and after to account for loss in pointing accuracy. Data collection will occur from 03:16:21-03:23:07.
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.
