There were RHESSI flares/GOES flares 186 / 32 over the time range 22-Dec-15 29-Dec-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 60% at the end of the most recent AGO pass today.
On 28 December (day 362) we skipped the playback pointer, during the second Wallops pass, dropping the level from 99% to 22% and then played down to 19%. This resulted in a vc3 data gap from approximately 04:30 UT to approximately 20:00 UT on 27-dec-2015.
The cold plates, 1 and 2 were at 137.5 and 136.0 K, on 2015-12-30.

Detector 2 is unsegmented, Detector 9 is off, detectors 3, 4, and 8 are not recording events. D3 was turned off beacuse it was filling the memory with front segment noise; D8 was turned off because it was filling the memory with rear segment ULD events.
