Solar Activity
Active region 11007 has been (relatively) active, producing two C-class flares that were observed by RHESSI. Unfortunately, it will shortly be going over the west limb.
How many GOES flares occurred? Flares above B, C, M, X class were 7 2 0 0 And how many of these are listed in the RHESSI flare list? Flares above B, C, M, X class were 3 2 0 0 And how many had EXCELLENT coverage? Flares above B, C, M, X class were 0 2 0 0 There were RHESSI flares/GOES flares 15 / 9 over the time range 29-Oct-08 05-Nov-08
Memory Management
The SSR is regularly emptying. The decimation is normal/active, front segment events are not being recorded in eclipse, and rear decimation is disabled in the northern magnetic zone.
Data Gaps
The data gaps on November 1 were from poor signal quality, and the data gap on November 4 was from a late acquisition, both at Wallops. The gap on November 4 is replayable.

Spacecraft Operations
Two items of note. First, the temperature of cold plate 2 is still increasing (97.6 K). Second, there was a mysterious step-function increase in the IDPU switched load current that appears to be traced back to the Crab operation in June. Mark is currently trying to figure out what may have changed. This increase in current is presumed to be the reason that the battery is now reaching a depth of discharge of 25%.
