Solar Activity
After the M flares of last week, solar activity dropped about a week ago (coincident with this tohban shift!) and is now slowly picking back up. Currently there are 4 active regions on the disk, one of which (AR 11620) is producing several C flares and 1 M flare today. Activity is likely to continue at this level, as STEREO B does not show any large, complex ARs about to rotate onto the disk.
How many GOES flares occurred?
Flares above B, C, M, X class were 8 29 2 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 5 18 2 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 2 7 0 0
Memory Management
Memory management is ok, with the SSR reaching a max of 22% and emptying at the end of each pass set. Decimation remains at normal/vigorous, and we are not collecting events at night.
Spacecraft Status
There were no significant changes in the cold plate temperatures or cryocooler power.
Data Gaps
There was one data gap (20 mins around 2012-11-22T05:00:00.000), with the data later filled in but showing some bad packets.
Detector issues
Detectors: there was one isolated spike in D4, which also gets a little spiky during the SAA, but nowhere near the wild behavior of D8. Other than that there was no unusual detector activity -- D8 is still showing increased counts coming out of the SAA and D2 is showing a light leak problem. Both of these are known issues and do not need correction at this time.
There were no changes to the detector settings this week.
