Solar Activity

The Sun has been very quiet after the subsidence of AR 11010 (which was a new-cycle region).

No GOES flares for Time Range

Memory Management

The SSR has been emptying a bit slower due to about one fewer pass per day on average. The decimation is normal/active and front-segment events are being recorded in eclipse.

Data Gaps

These data gaps are (primarily) due to bad data from Wallops LEO-T. They are supposedly fixing the problem.

GAP START TIME              GAP END TIME                   GAP (SEC)

Spacecraft Operations

The spacecraft was spun up and the high voltages on detectors 6 and 8 were reduced by 6 steps each. On January 19th, there was a command lock-out that resulted from bad telemetry data at Wallops, and the spacecraft needed to be manually commanded to override. On January 21st, the V-T curve for battery charging was changed.
