None
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 285K 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.
Non-MODIS Significant Events:
The EMOS mission status webpage (which includes instrument data loss
records) can be found at the following URL. Note that a password is now
required to access the EOS mission links web pages. There are directions
at the URL below for how to obtain a username/password.
