Tuesday, October 4, 20052005/277 20:13:30-20:22:18 ATC MOD_OA16_SDSM_SCRN_NO_DOOR_A.4
OA-16: SD/SDSM screened side A, no door movement.
2005/277 22:30:00-22:30:31 ATC MOD_SRCA_11_3_8_2_SETUP_CC.1
SRCA setup activity using lamp #4 in lieu of lamp #2 and in constant current feedback mode
2005/277 22:41:45-23:16:55 ATC MOD_OA19_SRCA_FULL_RAD_A.6
OA-19: SRCA Full Radiometric Calibration.
Data collection from 22:57:39-23:15:56.
Maneuvers:
The next Terra MODIS Lunar Calibration Roll will be on DOY 2005/294 (October 21, 2005). The roll angle will be -15.0593 degrees. Data collect will be from 22:30:47-22:37:17.
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 2005/266 at 14:36:43, TMON 16 tripped causing the science formatting equipment (SFE) to turn off. The FOT successfully turned back on the Science formatter at 19:46:37. Direct Broadcast was also turned back on at 20:40:05. Operations are currently running nominally. There will be no science data between 2005/266/14:36:43 and 19:46:37.
