Solar Activity
It was another quiet week. There are four active regions on the disk and nothing major about to rotate on. A few days ago there was a flurry of C flares, but that AR quickly rotated off. A new AR about to come on-disk is produced an occulted B flare, but quiet activity is expected to continue.
How many GOES flares occurred?
Flares above B, C, M, X class were 24 19 1 0
Memory Management
The SSR emptied after most pass set.
Spacecraft Status
A spin-up from 14.6 to 15.0 RPM was performed on 2013-086 between 18:23 and 19:30 UT.
Data Gaps
There is one data gap in VC3 data that cannot be replayed due to the SSR fill issue (?)

Detector issues
A similar event happened in November of 2011 (which was before the last anneal); see the tohban reports for more info. As with that event, the excess noise here is at low energies, as you can see in the first plot below.

Some plots illustrating the issue:
Other notes
The problem of quicklook generation processing has been fixed.
Decimation | Normal/vigorous |
HLAT Decimation | Rear decimation weight 6, no front decimation |
Night time data (fronts) | +/- 4 minutes |
Night time data (rears) | Taking data at nights |
Require extra passes? | No |
Requirement for moving pointer? | No |
Attenuator operation | Normal |
Detector problems? | Detector 5 arc + extended noise period. |
