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) 5) ~X9 around 20170910T16:30, where we missed the first half of the impulsive phase.
Several other <M5.0 flares also.
With the AR responsible for most of the activity disappearing over the limb, solar ctivity has severely decreased in the past few days, and is currently below B-level.
Memory Management
The SSR reached a maximum of ~82% (!) and a minimum of ~65% during the week.
We deleted the following time intervals (by moving the read pointer):
2017/09/04 07:00 - 2017/09/04 15:15 UTC 2017/09/05 05:31 - 2017/09/06 05:50 UTC
Spacecraft Status
Detectors 1, 3, 6 and 8 are active and taking data.
The cold plate 1 and 2 temperatures are XXX K and XXX K.
Currently the Cryocooler power is ~75.3 W and the acceleration is at ~11mg
Data Gaps
No apparent data gaps so far, but with the SSR full, we are lagging far behind.
= Detector issues
Other notes
A spin up was done. 2017-251-18:48 to 2017-251-19:14 UTC.
Spacecraft Management
| Decimation | Active/Vigorous |
| HLAT Decimation | Rear decimation |
| Night time data (fronts) | plus/minus 4 minutes from daylight |
| Night time data (rears) | plus/minus 4 minutes from daylight |
| Require extra passes? | No |
| Requirement for moving pointer? | No |
| Attenuator operation | logic enabled |
| Detector problems? | See notes above. |
