Solar Activity
Solar activity picked up this week, with most of the action coming from active region 11515 (but also 11512, 11513, and 11514). 11515 remains in the center of the disk, so won't be rotating off soon, but is starting to decay. So it's unclear if the Sun will stay active in the coming week. Several M class flares were caught by RHESSI.
How many GOES flares occurred?
Flares above B, C, M, X class were 14 49 9 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 5 27 4 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 3 18 3 0
There were RHESSI flares/GOES flares 308 / 72 over the time range 27-Jun-12 03-Jul-12
Memory Management
At the last Ops meeting the Sun was quiet and we had memory to spare, so we changed to a less vigorous decimation scheme and also started collecting all nighttime events. These steps, with the higher solar activity, caused the SSR fill to increase, with a maximum of 54%. At the end of the last pass set the fill was 32%. It was decided during today's meeting to change the nighttime collection back to only the first and last four minutes of the eclipse.
Spacecraft Status
Commands this week (all related to the memory issue):
- June 28th, 2200 UT: Decimation changed to active/vigorous
- June 28th, 2200 UT: Nighttime event collection enabled for both fronts and rears, entire eclipse
- July 2nd, 2130 UT: Decimation changed to active/vigorous
