This Week's Scheduled MODIS Activities Not Completed:
None
Upcoming MODIS Events:
Calibrations for October will include one SRCA spectral (DOY 279), one SRCA full radiometric (DOY 285), one PV ECal (DOY 284), one lunar roll (DOY 281), and one screened SD/SDSM (DOY 286).
Maneuvers:
None
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:
Terra lost a contact to the ISS on Tuesday (DOY 265), resulting in the following brief periods of data loss:
265/09:20:07-09:20:21
265/09:20:31-09:21:12
265/11:09:57-11:21:09
