Solar Activity

Solar activity was relatively low this week, generally at B-level with 26 C-class flares. There are currently 9 ARs on the disk and the largest AR is near the center of the disk. STEREO B shows a few bright regions that would rotate on disk in the next few days.

How many GOES flares occurred?

 Flares above B, C, M, X class were      1    26     1     0

And how many of these are listed in the RHESSI flare list?

 Flares above B, C, M, X class were      0    17     1     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      0     8     1     0

There were RHESSI flares/GOES flares 292 / 28 over the time range 16-Sep-14 23-Sep-14


Memory Management

RHESSI returned to NORMAL/VIGOROUS mode this week. SSR is ...

Spacecraft Status

Detector issues

Detector 2 continued to have the light leak problem. Raised the front fast threshold from 0x50 to 0x60.
