Some activity, including a couple of M flares. Activity has been quieter the last couple of days:
How many GOES flares occurred?
Flares above B, C, M, X class were 16 51 4 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 7 32 3 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 5 16 2 0
There were RHESSI flares/GOES flares 142 / 71 over the time range 13-Oct-15 20-Oct-15
Decimation was active/vigorous for the full time period. Both front and rear detectors are off during SC night, except for 4 minutes on either side. The SSR is at 29%, with 6 contacts left for the day, and has been dropping to about 13% after each day's set of passes.
The cold plates, 1 and 2 were at 135.1 and 133.6 K, on 2015-10-19.

Detectors 2 is unsegmented. Detector 4 is not recording events. Detector 9 is off. No threshold or high-voltage changes were made. Live time for each ok detector has increased throughout the week, including D8f, which has increased from ~0.45 live time to ~0.6. The reset rate on D8r is very high, but has dropped over the past week from 2.5e5 to 1.5e5.
Attenuator logic seems to be working as expected for the thin attenuator. There were no thick attenuator motions this week.
