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.
