Solar Activity
Solar activity remained low this week, with a few C class events. The forecast is for continued low activity, with a slight chance for an M class flare from region 11805. There are no large regions preparing to rotate on disk.
How many GOES flares occurred?
Flares above B, C, M, X class were 17 17 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 9 11 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 5 5 0 0
There were RHESSI flares/GOES flares 211 / 34 over the time range 23-Jul-13 30-Jul-13
Memory Management
The SSR has mostly emptied during passes, during one pass it remained at <1%. Since activity is low and SSR is emptying, we continued to take data during the entire night.
Spacecraft Status
The cold plates, 1 and 2 were at 116.965 K and 115.4 K respectively. During passes it was seen that the cold plate 1 occasionally crept up past 117 K and was marked in orange in the observing status page.
Data Gaps
The monitor rates gaps from 29th/30th have not been filled in yet.

Detector issues
Detector 7's HV was lowered by 10 steps on July 24, 2013 (day 205) at 19:29:15 UTC, it is currently at ~3800 V. This voltage change did not fix the noise issue in detector 7.
At the last meeting there was mention of adjusting detector 7 threshold if the HV change was not sucessful. Since the noise issue was not filling up SSR, or effecting other detectors, no action on the thresholding was taken until further group discussion at this week's meeting.
Other notes
Eclipse event data was enabled for fronts and rears on July 26th. Spin-up completed between 17:35:34 and 19:17:55 UTC on July 25th.
