Solar Activity
This week was quiet, aside for two high-B flares on Sunday and Monday.
How many GOES flares occurred?
Flares above B, C, M, X class were 17 3 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 9 3 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 4 1 0 0
There were RHESSI flares/GOES flares 17 / 20 over the time range 21-Feb-17 28-Feb-17
Memory Management
Memory seems steady at ~25% at end of pass daily set.
Decimation was normal/vigorous.
BGS station is still in the red for downlink. Still unclear what the issue is. Besides VC2 dumps, the quickest way to see what Monitor Rates are doing is the VC1 plots generated by Albert. They might not show much for AGO passes, though, due to SAA. Better for WLP passes.
Spacecraft Status
D3 and D6 are on. Cryocooler power is still at 75W.
Attenuator average deadtime: currently 14.9%, I've seen 15.9% peak.
17-053-23:39:39 start attenuator013_bg ; set to 16.5%

Detector issues
D6f livetime has been dropping fairly fast. F6f fast thresholds were commanded from 0x90 to 0xB0 on Feb 28th:

...but it looks like we will need another increase as soon as we get monitor rate information during the above change.
