How many GOES flares occurred?

 Flares above B, C, M, X class were      5     2     0     0

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

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

And how many had EXCELLENT coverage?

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

There were RHESSI flares/GOES flares 3 / 7 over the time range 12-Sep-17 19-Sep-17

Memory Management

Decimation was active/vigorous for the full time period, with the SSR level currently at 41%, recovering from the previous week's activity. We are approximately 2 days behind recovering data.

Spacecraft Status

Detectors 1, 3, 6, and 8 are recording events. The cold tips are 131.4 and 129.6 K as of 19-sep-2017. The cold plates, 1 and 2 are 156.8 and 155.4 K. Cryocooler power is steady at 74.1W, cryocooler efficiencies are 0.0271 and 0.0275. 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 or HV changes.
