Solar activity dropped off this week following an X-class event on Sept 9. Solar activity is moderate, with a handful of C class events in the past 24 hours. Most of these events, and the most complicated magnetic spot on disk, is on the western limb. Activity should remain low as there are no complex spots set to rotate on disk in the next few days. | Solar activity dropped off this week following an X-class event on Sept 9.

Solar Activity
Solar activity dropped off this week following an X-class event on Sept 9. Solar activity is moderate, with a handful of C class events in the past 24 hours. Most of these events, and the most complicated magnetic spot on disk, is on the western limb. Activity should remain low as there are no complex spots set to rotate on disk in the next few days.
How many GOES flares occurred?
Flares above B, C, M, X class were 2 29 3 1
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 1 20 3 1
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 0 9 1 0
There were RHESSI flares/GOES flares
Memory Management
RHESSI continues in ACTIVE/VIGOROUS mode this week, and did not have a mode change for the coordinated NuStar observations. We turned full nighttime events back on after the ops meeting on wednesday. SSR is emptying at the end of the pass set with a few extra, and reached a maximum of 20%.
Nighttime events turned back on: 2014-255-20:16:40 UTC
Spacecraft Status
Spacecraft systems are nominal. Cold plate temps are 125.4 and 124.2, up slightly from last week, as expected from shadow length duration. Temperatures should start dropping again as of next tuesday/wednesday. Attenuator motion was nominal. Cryocooler is nominal.

No Monitor rates gaps for this time period
Detector issues
Detector 9: Some isolated spikes in the rear segment. These were not frequent or extreme enough to warrant a voltage change, although the next Tohban should keep an eye on it.
Detector 2: Raised the Front Fast threshold due to the light leak. 14-260-16:36:36 /IDPUTABLE2 OFFSET=FRONTFASTDAC 14-260-16:36:51 /IDPULOAD VALUE=0x50
Spacecraft Operations
Decimation remained in ACTIVE/VIGOROUS this week. We will change into NORMAL/VIGOROUS after the ops meeting.
Other notes
| Decimation | Active/Vigorous |
| HLAT Decimation | Rear decimation weight 6, no front decimation |
| Night time data (fronts) | full nighttime events |
| Night time data (rears) | full nighttime events |
| Attenuator operation | Active |
| Detector problems? | Noise in 9, light leak in 2 |
