This Month’s Upcoming MODIS Events:
December activities will include a Lunar Roll (356), another SD/SDSM (358), and another SRCA Rad (364). January 2014 activities will include a SD/SDSM (014), a SRCA Spatial (022), a SRCA Spectral (022), and an SRCA Radiometric (027). Additionally, there will be a Terra Lunar Roll (TBD), a 1 W Rad (TBD). Please note that most likely either the Spatial or Spectral will be moved from 022.

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.
