Solar Activity
We have flares!! Activity is high this week with an X5 flare produced on 03/06/12. NOAA 11429 is a large beta-gamma-delta region with up to five significant penumbral spots. NOAA 11430 is an EFR thats growing just to the west of 11429 and may produce some sympathetic flaring events between the two regions. Hopefully activity won't die down until the region passes.
How many GOES flares occurred?
Flares above B, C, M, X class were 10 38 12 3
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 4 10 3 1
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 2 6 1 0
There were RHESSI flares/GOES flares 172 / 63 over the time range 29-Feb-12 07-Mar-12
Memory Management
We had major problems with the SSR this week. It reached a maximum of 99.6% during the X5. See below for explanation.

Spacecraft Status
03/04/12 - 03/05/12 The SSR was noted to be at 96% on Sunday night and action was taken to change the decimation to active vigorous. This didn't have much effect to a days worth of Ago passes were added. The fast rates were accidentally set to force on instead of auto on when it was noted they weren't turned back on after the anneal.
It was established that the attenuators were not moving and so the thin attenuator was forced in place. Following an ADP reset, the attenuators were found to be working automatically again. however, just to be on the safe side, they two attenuators were forced in to try to empty out the SSR which was rising faster than we could empty (despite all the extra passes). Finally we decided to dump data to make space in the SSR which was back at 90%.
