Solar Activity

Solar activity was relatively low this week, generally at B-level with 26 C-class flares and 1 M-class flare. There are currently 9 ARs on 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 emptying out at the end of daily pass sets with maximum 32% (occurred on Sep.20).

Spacecraft Status

Spacecraft systems are nominal. Cold plate temps are 125.8 and 124.3 and should come down as daylight length decreases. Attenuator motion was nominal. Cryocooler is nominal.

Data Gaps

There was one VC3 data gap 9000sec = 2.5 hrs on Sep 18. It was due to a processing glitch but has been fixed by Jim McTiernan who commented that

 The file vc3_20140919111353.0 fills the gap. It was never processed, and it in the hold_itos_pkts directory 
 (How it got there without processing, or sending an error message to me is a mystery)

2014-09-18T21:30:00.000 -- 2014-09-19T00:00:00.000 9000.0000

Besides this issue, BGS hung up on Sep. 23 but the data were replayed without any problem.

Detector issues

The light leak problem with Detector 2 has improved significantly after changing the front fast threshold from 0x50 to 0x60 on Sep. 22. Further threshold changes are not necessary but the problem persists and the next tohban should keep an eye on it.
