Solar Activity

Early activity, quiet for the last few days.

How many GOES flares occurred?

 Flares above B, C, M, X class were     41    18     0     0

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

 Flares above B, C, M, X class were     20    13     0     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were     10     5     0     0

There were RHESSI flares/GOES flares 126 / 59 over the time range 30-May-17 06-Jun-17

Memory Management

Decimation was active/vigorous for the full time period, with the SSR level steadily decreasing from a high of 78%, down to 23% currently.

Spacecraft Status

Detectors 1, 3, 6, and 8 are recording events. The cold tips are 128.4 and 126.7 K as of 6-jun-2017. The cold plates, 1 and 2 are 154.1 and 152.7 K. Cryocooler power is steady at 74.7 W, cryocooler efficiencies are 0.0273 and 0.0277. See:
