Solar Activity
QUIET!
How many GOES flares occurred?
Flares above B, C, M, X class were 1 0 0 0
RHESSI flare list contains 0 over the time range 21-Nov-17 28-Nov-17
Memory Management
Decimation was active/vigorous for the full time period, with the SSR level typically below 20%.
Spacecraft Status
Detectors 1, 3, 6, and 8 are recording events. The cold tips are 132.6 and 130.8 K as of 6-nov-2017. The cold plates, 1 and 2 are 157.1 and 155.6 K. Cryocooler power is steady at 74.3W, cryocooler efficiencies are 0.0264 and 0.0277. See:

for a summary plot of recent temperatures, efficiencies and accelerometer values.

Detector issues
Detectors 1, 3, 6, and 8 are powered on, and are recording events. No threshold changes or HV changes this past week. The attenuator dead time threshold was reduced to 18% on 22 November.
