Solar Activity
Solar activity was rather low this week. Currently there are three active regions that just showed up on the east limb. Activity is not expected to be so high next couple of days. The major flare this week was a M7.2 that RHESSI observed during its decay phase.
How many GOES flares occurred?
Flares above B, C, M, X class were 19 19 1 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 10 12 1 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 0 0 0 0
There were RHESSI flares/GOES flares 301 / 39 over the time range 23-Jun-15 30-Jun-15
Memory Management
SSR fill was pretty low this week, usually below 40%. On June 29 the were some spikes in the SSR filling that I would like to discuss.
Spacecraft Status
Normal as far as the Tohban can tell.
Data Gaps
There have been a bounch of small data gap during last week. [[1][2][3][4][5][6]]
Detector issues
En general detectors were stable this week, no changes were needed. Light leak is still observed on the Front segment of detector 2. D8 and D9 front livetime are still showing low values.
Attenuator management
Last Wednesday June 24 we increased the threshold used to put the thin attenuator IN (A0 to A1). We went from a value of 5.1 % to 10 % That change took effect 2015-175-22:12:56 UTC. We agreed in to perform this experiment for about one month, it means that by July 22 we should asses how well this changed worked.
Spacecraft Management
Spin-up
We're still in Active/Vigorous decimation, and still taking events at night.
| Decimation | Active/Vigorous |
| Night time data (fronts) | Taking night events |
| Night time data (rears) | Taking night events |
| Require extra passes? | No |
| Requirement for moving pointer? | Some replaying |
| Attenuator operation | Still trying to optimize motions. |
