Solar Activity
The Sun was very active produced a string X-flares this week!!
How many GOES flares occurred?
Flares above B, C, M, X class were 0 55 27 4
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 0 25 17 3
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 0 13 8 1
There were RHESSI flares/GOES flares 214 / 86 over the time range 04-Sep-17 11-Sep-17
1) X2.2 around 20170906T09:00. GOES 15 data seems to be missing for part of that one, but we have good RHESSI coverage of the impulsive phase. 2) X9.3 around 20170906T12:00, three hours later. Missed all of the impulsive phase due to SAA. 3) X1.3 around 20170907T14:35 (missed most of it due to SAA) 4) M8,3 around 20170908T07:48 (missed the impulsive phase due to SAA)
Several mid to high M-flares also.
Memory Management
The SSR reached a maximum of ~70 percent and a minimum of ~30% during the week.
Spacecraft Status
Detectors 1, 3, 6 and 8 are active and taking data.
The cold plate 1 and 2 temperatures are ~156.5K and 154.8K.
Currently the Cryocooler power is ~75.3 W and the acceleration is at ~11mg
Data Gaps
No data gaps this week.
= Detector issues
Other notes
The attenuator logic threshold was changed on 2017-248-18:48:33 UTC.
The new thresholds are as follows:
0.00 Min A0 23.14 Max A0 <- thin in 19.60 Min A1 <- thin out 25.10 Max A1 <- thick in 18.82 Min A2 32.94 Max A2 20.39 Min A3 <- thick out 100.0 Max A3
