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:

http://sprg.ssl.berkeley.edu/~ayshih/soh/latest_temperatures.pdf

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