Solar Activity
B-flare activity How many GOES flares occurred?
Flares above B, C, M, X class were 6 0 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 2 0 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 1 0 0 0
There were RHESSI flares/GOES flares 4 / 6 over the time range 16-Nov-16 23-Nov-16
Memory Management
Decimation was normal/vigorous for the full time period. The SSR was at 30% at the end of daily passes. Detectors 3 and 9 are on full-time, including spacecraft night, and rear segment decimation was on in hgi-latitude regions.
Spacecraft Status
Detectors 3 and 9 are recording events. The cold tips are 120.3 and 118.5 K as of 2016-11-23. The cold plates, 1 and 2 are 144.7 and 143.2 K. Cryocooler power is steady at 86W, cryocooler efficiencies have decreased over the last week from 0.027 to 0.026.
Data Gaps
The many short data gaps are due to noisy data connections.

Detector issues
Detectors 3 and 9 are powered on, and are recording events. No threshold or HV canges during the week.
