Flares above B, C, M, X class were 13 7 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 8 3 0 0
There were RHESSI flares/GOES flares 54 / 41 over the time range 05-Apr-17 12-Apr-17
Memory Management
The SSR reached a maximum of ~70 percent during the week. Currently is about 60%
Spacecraft Status
During most of the week detectors 1, 3, 6 and 8 were active and taking data, but since 11-Apr-2017 only detectors 3 and 6 are active. The cold plate 1 and 2 temperatures are ~153.1K and 151.5K.
Decrease the attenuator threshold to 12.5% deadtime.
Currently the Cryocooler power is ~75.7 W and the acceleration is at ~11mg
