Solar Activity

Quiet Sun up until yesterday:

How many GOES flares occurred?

 Flares above B, C, M, X class were      1     0     0     0

And how many of these are listed in the RHESSI flare list?

 Flares above B, C, M, X class were      1     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 1 / 1 over the time range 14-Mar-17 21-Mar-17

Memory Management

Decimation was normal/vigorous for the full time period, with the SSR at 0% at the end of each day's contacts.

Spacecraft Status

Detectors 3 and 6 are recording events. The cold tips are 127.9 and 126.1 K as of 17-Jan-2017. The cold plates, 1 and 2 are 153.5 and 152.0 K. Cryocooler power is steady at 75W, cryocooler efficiencies are 0.0275 and 0.0279. See:

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