Solar Activity

Solar activity was low this week with only minor C class flares occurring despite the presence of a beta-gamma-delta region for much of the week. All regions on disk are currently in decay however, a large active region is just behind the east limb and may bring more activity.

How many GOES flares occurred?

Flares above B, C, M, X class were     35     8     0     0

And how many of these are listed in the RHESSI flare list?

Flares above B, C, M, X class were     21     7     0     0

And how many had EXCELLENT coverage?

Flares above B, C, M, X class were     12     3     0     0

There were RHESSI flares/GOES flares 159 / 43 over the time range 17-Aug-11 24-Aug-11


Memory Management

The SSR is emptying at the end of the daily passes, max 6%.

Data Gaps

There were no data gaps this week.

Spacecraft Status

We remain in normal/vigorous decimation mode. Spin rate is 14.9. Cold plate 2 and CPC temperatures are being affected by the long spacecraft days (99 K and 60 C respectively).

Detector 8 showed further bouts of high noise, the latest one being at 13:30UT on the 23rd. This was around the time the HV was lowered by 6 steps to 189 although whether it was before or after is not yet clear.
