Maneuvers:
---
Terra Lunar Roll took place on 2020/280 and 2020/283.
Terra DMU #124 will take place on 2020/302.

MODIS Anomalies:
---
On October 05, 2020 (2020/279) at 15:21:12 GMT, Terra noted a single-event upset which caused a failure on PWA-41, made up of supersets 80 and 81.

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.
