Solar Activity

Some activity:

How many GOES flares occurred?

 Flares above B, C, M, X class were     28     2     0     0

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

 Flares above B, C, M, X class were     14     2     0     0

And how many had EXCELLENT coverage?

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

There were RHESSI flares/GOES flares 54 / 30 over the time range 18-Apr-17 25-Apr-17

Memory Management

Decimation was active/vigorous for the full time period, with the SSR level slowly increasing, at 57% prior to today's WPS and BGS contacts.

Spacecraft Status

Detectors 1, 3, 6, and 8 are recording events. The cold tips are 130.5 and 128.6 K as of 25-apr-2017. The cold plates, 1 and 2 are 155.9 and 154.5 K. Cryocooler power is steady at 75W, cryocooler efficiencies are 0.0275 and 0.0271. See:

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

Data Gaps

Many gaps post 2017-04-22 due to noisy data:

Detector issues

Detectors 1, 3, 6, and 8 are powered on, and are recording events. The front fast rate threshold on D1 was increased from 0x80 to 0x90 on 25-Apr-2017 to increase livetime. The front fast rate threshold on D8 was increased from 0x90 to 0xB0 on 25-Apr-2017 to increase livetime.

Notes

Noisy data has resulted in some apparent attenuator state changes shown on qlook plots.
