Solar activity was very low this week with a GOES base level to be at about B3. There are currently 4 ARs on the disk. AR12396 shows some magnetic complexity but it will rotate off the disk in a couple of days.
How many GOES flares occurred?
Flares above B, C, M, X class were 19 20 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 12 13 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 5 3 0 0
There were RHESSI flares/GOES flares 183 / 39 over the time range 05-Aug-15 12-Aug-15
The SSR fill levels where between about 0 and 30%.
The cold plate 1 and 2 are at about 130 K and 129 K respectively.

No commanding has been performed this week. Detector performance appeared to be stable this week.
Three topics have been identified to possibly take action on:
Detector 9F livetime is currently at about 45%. The fast threshold could be in creased until a significant increase in livetime can be recorded.
Detector 4F and 6F shows elevated front slow and reset rates, but relatively low front fast rates.
We decided to raise 4F slow threshold from 0x70 to 0x80.
We had two Spin-rate anomalies; see following timeline:
2015-221-16:36 Spin too low, transitioned to idle 2015-221-23:24 Precession mode 2015-222-00:04 idle mode, due to another spin anomaly 2015-222-02:32 idle to spin 2015-222-04:03 spin to precession 2015-222-05:20 precession to normal
Following the precession-to-normal transition, a Spin-up has been preformed between 02:32 and 04:08 UTC on Aug 10, 2015.
The Att.3 threshold has not been adjusted yet due to the timing of BGS passes.
