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
2017-129-19:07:33 /IDPUTABLE3 OFFSET=FRONTFASTDAC
2017-129-19:08:19 /IDPULOAD VALUE=0xD0 ; was 0xB0
2017-129-19:08:36 /IDPUTABLE8 OFFSET=FRONTFASTDAC
2017-129-19:08:43 /IDPULOAD VALUE=0xE0 ; was 0xC0

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