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. [Why not quiet/vigorous, so we do not decimate?]
BGS station is still in the red for downlink. Still unclear what the issue is. This means we never know when what the monitor rates are until a few days after the fact, unless we specifically ask for VC2 dumps. Perhaps we sould have them automatically while BGS is down?
Spacecraft Status
D3 and D6 are on. Cryocooler power is still at 75W.
From Nicole's notes last week: The background flux is up at 12%, and the out shutter is set to ~15%. We still have margin, but Ops suggest that we adjust this. The idea is that we will raise the thin shutter out threshold to 5% above the current deadtime, so we will raise it to ~17%. ==> I have seen almost 16% on the status page.

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.
Memory Management
It looks like D6 page has not been updated: its voltage still indicated to be zero currently!
