The Sun has been very quiet after the subsidence of AR 11010 (which was a new-cycle region).
No GOES flares for Time Range
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.
These data gaps are (primarily) due to bad data from Wallops LEO-T. They are supposedly fixing the problem.

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.
