Solar Activity

Solar activity was high this week! We had the largest flare of the current solar cycle on the 9th August - an X7 which RHESSI observed. This came from NOAA 11263 which has today, rotated off the disk. STEREO B does not show any significant regions approaching the limb and those already on disk are not particularly complicated. There were multiple M class flares, though RHESSI missed the impulsive phase of most of these.

How many GOES flares occurred?

Flares above B, C, M, X class were     20    44     4     1

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

Flares above B, C, M, X class were     13    24     3     1

And how many had EXCELLENT coverage?

Flares above B, C, M, X class were      9    10     0     1

There were RHESSI flares/GOES flares 340 / 69 over the time range 03-Aug-11 10-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 had yet another burst of unusual behaviour on 8-Aug-2011 at ~18:55UT. This was observed in both the fronts and rears just before an eclipse.
