Solar Activity
Solar activity was very low this week, there haven't been any flares in the past two days. There are currently two active regions on disk, neither of which have produced any flares to date. Stereo B shows at least one active region to rotate on disk in the next week.
How many GOES flares occurred?
Flares above B, C, M, X class were 17 12 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 9 6 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 6 3 0 0
There were RHESSI flares/GOES flares 173 / 29 over the time range 03-Sep-13 10-Sep-13
Memory Management
The SSR is emptying, or getting within 1%, at the end of the pass set.
Spacecraft Status
Spacecraft status is nominal. The cold plate 1 and 2 are at 116.8 K and 115.2 K respectively.
Data Gaps
These were all filled in Browser.

Detector issues
No additional D2 or D1 spikes were seen.
There were 3 spikes that occured throughout the detectors and also appeared in the particle rates, suggesting they were the result of a corrupted packet (not an actual spacecraft issue). These occurred on Sept 5th at 05:36:10UT and on Sept 7th at 00:53:58UT and 1:11:30UT.
The D9 rear segment noise returned this week. The brief dropouts grew in strength, reaching a maximum on the 9th. Their severity was no greater than in the past and there were no tangible consequences to SSR or livetime, so no action was taken. The severity and duration has begun to decrease and as of the 10th, was comparable to those seen on the 4th.
