Solar Activity
Little activity of note:
How many GOES flares occurred?
Flares above B, C, M, X class were 14 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 4 / 14 over the time range 02-May-17 09-May-17
Memory Management
Decimation was active/vigorous for the full time period. SSR at 52% with 4 passes to go today.
Spacecraft Status
Detectors 1, 3, 6, and 8 are recording events.
See http://sprg.ssl.berkeley.edu/~ayshih/soh/latest_temperatures.pdf for a summary plot of recent temperatures, efficiencies and accelerometer values.
Data Gaps
Large data gaps in only the last 1.5 days -- presumably because the data has not been downloaded yet. No data gaps of note beyond that this week.
Detector issues
Detectors 1, 3, 6, and 8 are powered on, and are recording events. To increase livetime, the following fast threshold changes have been made this week:
2017-129-19:06:45 /IDPUTABLE1 OFFSET=FRONTFASTDAC 2017-129-19:06:57 /IDPULOAD VALUE=0xE0 ; was 0xA0

Some of the detector entries in the RHESSI Wiki had not been properly updated.
