Solar Activity
The sun was very quiet this past week. The big event was a small M-class flare on June 02. Note that although this flare was registered as M-class in GOES, hsi_tohban_flare_counter did not recognize an M-class event during this time period. The active region that produced this M and 2 C events, 12077, is near disk-center and will be on disk for the next week. The remaining 4 ARs on disk have had no flaring activity. By late in the next week, an AR should rotate on disk.
How many GOES flares occurred?
Flares above B, C, M, X class were 11 8 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 8 8 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 5 3 0 0
There were RHESSI flares/GOES flares 47 / 19 over the time range 27-May-14 03-Jun-14
Memory Management
The SSR is emptying at the end of the pass set, with a max fill of 31%. It is emptying just at the end of the pass set.
We're still in Active/Vigorous decimation. Eventhough we have relatively little solar activity, the SSR is still filling with detector noise counts.
Spacecraft Status
The cold plate 1 and 2 are at 118.9 K and 117.4 K respectively. Spin rate 14.8.

Detector issues
The detectors kept evolving this week. Brief changes are noted here, exact times and commands are on the Detector pages
D1: Rear Fast 0x60
D2: Same noise character as D3. Livetime decreases over a RHESSI day by as much as 10%. Could this be related to the light leak?
D3: Rear fast threshold change, to 0x75. Decision made based on high fast rates and correspondingly low livetime. Front 0x20.
D4: Front fast to 0xB0
D5: Front fast threshold change, to 0x60.
D6: HV decreased by 10 counts, to 1500 V.
D9: At last week's meeting we decided to keep it at ~1000V following the HV test.
shutters: Thin shutter locked in after the M event on Jun 2. D1's noise increase was blamed. Changed shutter logic to twice on D2 and twice on D5
Other notes
Shutter locked in on Jun 2
