Solar Activity

Solar activity was very high in the early part of this week. NOAA 11283 produced lots of big flares, including one more X class and 3 more M class. Activity is low at the moment but NOAA 11296/11296 (a big complex region just rotated on disk) shows promise.

How many GOES flares occurred?

Flares above B, C, M, X class were     7     17     3     1

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

Flares above B, C, M, X class were     4     16     3    1

And how many had EXCELLENT coverage?

Flares above B, C, M, X class were     4     9     2     1

There were RHESSI flares/GOES flares 257 / 31 over the time range 07-Sep-11 14-Sep-11

Memory Management

The SSR is emptying at the end of the daily passes, max 22%. To ensure the SSR was emptying during the high activity last week, decimation was set to active/vigorous. With the rotation of the large AR off the disk, I think its safe to return to normal/vigorous although NOAA 11295/11296 should be monitored. As per David Smiths request, night time events can be initiated.

Data Gaps

There were no data gaps this week.

Spacecraft Status

Similar to that reported last week, there was a small isolated spike in G6 fronts on 11-09-2011 at ~05:25 UT http://sprg.ssl.berkeley.edu/~tohban/browser/?show=grth+qlpcr+qlpfr+qlprr+monfs+monfr+monff&date=20110911&time=052614
