Solar Activity
The Sun was moderately active this week. Of particular note was a long-duration M flare on Sept. 9, which caused a Major Flare Watch to be called. However, there were no further large events. Instead, activity quieted a little after the M flare. The base GOES level is currently in the high B-class, down from C1 a few days ago. Moderate activity is expected to continue in the upcoming days, since the two largest flaring regions (12157 and 12158) are still on the disk.
Memory Management
We have been in Active/Vigorous decimation all week, and are retaining nighttime events. Extra passes were put in over the weekend in order to ease the SSR fill. We were almost emptying before the M flare, which added a large fill since it was a long-duration flare. As of this writing (6:45 am PDT) we are at 25%, with several passes to go today.
