Solar Activity

B-flare activity:

How many GOES flares occurred? 

 Flares above B, C, M, X class were     17     0     0     0

And how many of these are listed in the RHESSI flare list? 

 Flares above B, C, M, X class were      2     0     0     0

And how many had EXCELLENT coverage? 

 Flares above B, C, M, X class were      2     0     0     0

There were RHESSI flares/GOES flares 5 / 17 over the time range 13-Sep-16 20-Sep-16

Note the the RHESSI flare count is underestiamted; the RHESSI flare list has not been populated since 15 September 2016 due to a missing ADP aspect parameter table in the ground software.

Memory Management

Decimation was normal/vigorous for the full time period. The SSR was at 7% 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 115.6 and 112.7 K as of 2016-09-19. The cold plates, 1 and 2 are 137.8 and 136.3 K. Cryocooler power is steady at 86W, cryocooler efficiencies are steady at 0.027. Minimum battery voltage is steady between 26 and 26.5 V.

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. No excess large numbers of resets or fast or slow rates at present. No changes were made to thresholds. All other detectors are off.

Other notes

The 6-8 keV background line that has been present recently seems not to be related to tapping in the cooling system. It is intermittent, only showing up during periods of high background, and power spectrum analysis of the time behavior shows no peak at the cryocooler frequency of 59.9 Hz.
