Sunday, February 23, 2014
2014/054 21:10:16-21:12:47 ATC MOD_OA27_PV_ECAL.3
OA-27: Photovoltaic bands electronics calibration.
Centered on S/C maximum latitude.
Monday, February 24, 2014

SRCA setup activity using 10W lamps 1 and 4, and 1W lamp 5, in constant current feedback mode
2014/055 21:08:38-21:40:03 ATC MOD_OA19_SRCA_FULL_RAD.1
OA-19: SRCA Full Radiometric Calibration.
Data collection 21:24:39-21:40:02.
S/C Night 21:15:19-21:48:23.
Tuesday, February 25, 2014
2014/056 20:52:47-21:01:35 ATC MOD_OA16_SDSM_SCRN_NO_DOOR_A.4

Maneuvers:
LR 2014/050 - 10:57:00 - 11:13:54
IAM 2014/052 – THIS MANEUVER WAS WAIVED, rescheduled for 057. Although the NAD and SV doors were scheduled to close, they were inhibited by the FOT. The end result is that MODIS was in nominal science all day on 052.
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.
