List all reports


Solar Activity

The activity was moderate early in the week, producing numerous C-class flares and 3 M-class flares. However, it became very quiet later this week. There are currently 4 active regions on the disk and STEREO B shows there may be one active region rotating on disk within the next few days.

How many GOES flares occurred?

 Flares above B, C, M, X class were      3    45     3     1

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

 Flares above B, C, M, X class were      2    32     2     0

And how many had EXCELLENT coverage?

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

There were RHESSI flares/GOES flares 265 / 52 over the time range 19-Nov-13 26-Nov-13

Memory Management

No issues. SSR max was 25%; it's emptying by the end of each pass set.

Spacecraft Status

Cold plates 1 and 2 are at 118.3 and 116.9, respectively.

Spin rate is 14.6; a spinup should be performed after the holiday.

Data Gaps

There was a data gap due to the CPU reset. (DOY 330, 17:54-17:59 UT)

Detector issues


Other notes

RHESSI experienced an autonomous CPU reset. The reset happened at 2013-330-17:54:27 UTC (November 26), during a ground station contact. The CPU came back up shortly thereafter at 17:54:58. This incident cleared all RAM. All stored commands and parameter tables used by the spacecraft were quickly restored during the 23:08 UT Wallops pass of DOY 330.
