Solar Activity
B-flare activity, that does not seem to be showing up in our local GOES database.
How many GOES flares occurred?
Flares above B, C, M, X class were 1 0 0 0
RHESSI flare list contains 19 over the time range 04-Oct-16 11-Oct-16
Memory Management
Decimation was normal/vigorous for the full time period. The SSR was at 0% at the end of BGS passes. Detectors 3 and 8 are on full-time, including spacecraft night, and rear segment decimation is turned off.
Spacecraft Status
Detectors 3 and 8 are recording events. The cold tips are currently 119.8 and 118.0 K as of 2016-09-19. The cold plates, 1 and 2 are 144.7 and 143.3 K. Cryocooler power is steady at 86W, cryocooler efficiencies have decreased over the last week to 0.026. Minimum battery voltage has increased to 27 V, presumably because we are no longer sending data during eclipses.
Data Gaps
The many short data gaps are due to noisy data connections.

Detector issues
Detectors 3 and 8 are powered on, and are recording events. Thresholds and HV's were changed for both detectors. On 7 October 2016, the G8 Rear fast threshold was increased from 0x70 to 0x80. On 9 October 2016, the G3 front slow threshold was increased to 0x30, the G3 front fast threshold was increased to 0x60, and the G3 rear fast threshold was increased to 0xA0. On 9 October 2016, the G8 front slow threshold was increased to 0x30, the G8 front fast threshold was increased to 0x40, and the G8 rear fast threshold was increased to 0xA0. On 10 OCtober 2016 the G3 and G8 front slow thresholds were reduced back to 0x0C. On 11 October the HV for both detectors was lowered to 2990 V.
Notes
During the 9-October-2016, 21:19 UTC pass, the thin attenuators were still stuck IN, so the thresholds were increased. The thin attenuators then popped right out. Also we increased the temperature limit, for shutting off the high voltage from 150K to 175K.
