Solar Activity

Some moderate activity, including an M flare, which RHESSI missed, except for the decay.

How many GOES flares occurred?

 Flares above B, C, M, X class were     45    21     1     0

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

 Flares above B, C, M, X class were     20    17     1     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were     10     8     0     0

There were RHESSI flares/GOES flares 129 / 67 over the time range 15-Aug-17 22-Aug-17

Memory Management

Decimation was active/vigorous for the full time period, with the SSR level currently at 25%

Spacecraft Status

Detectors 1, 3, 6, and 8 are recording events. The cold tips are 129.4 and 127.5 K as of 21-aug-2017. The cold plates, 1 and 2 are 156.9 and 155.4 K. Cryocooler power is steady at 74.1W, cryocooler efficiencies are 0.0277 and 0.0281. 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. A number of front slow threshold increases were performed on 16-Aug-2017, resulting in the front thresholds for detectors 1, 3, 6, 8 being set to, 0x15, 0x1C, 0x1C, and 0x20, respectively:
