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 47 8 1 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 29 5 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 16 2 0 0
There were RHESSI flares/GOES flares 104 / 56 over the time range 04-Jul-17 11-Jul-17
Memory Management
Decimation was active/vigorous for the full time period, with the SSR level currently at 27%
Spacecraft Status
Detectors 1, 3, 6, and 8 are recording events. The cold tips are 130.3 and 128.5 K as of 10-jul-2017. The cold plates, 1 and 2 are 155.7 and 154.2 K. Cryocooler power is steady at 74.7W, cryocooler efficiencies are 0.0271 and 0.0269. See:

Detector issues
Detectors 1, 3, 6, and 8 are powered on, and are recording events. HV for detector 1 was dropped to 1500 V on 2017-07-05.
2017-186-20:23:58 start attenuator013_bg ; was at 19.2%, set to 23.5%
Notes
On 2017-07-05, the attenuator thresholds were changed, to reflect a new background of 23.5% deadtime.
2017-186-20:24:49 /IHVDAC DETECTOR=1, VOLTAGE=78 ; was ~2000V, set to ~1500V
