General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody nominally maintained at 290K and the Solar Diffuser Door at the Screened position.
Note that the BlackBody will be maintained at 285K.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
