List all reports


Solar Activity

Solar activity was moderate this week with 3 M class flares. Currently there are 8 active regions on disk. Active region 12209, which hosted the X and M class flares on its previous rotation (then label 12192) is at the center or the disk, and is classified as a beta/gamma/delta region. A major flare watch remains in place, with a good chance for a >M5 class flare.

How many GOES flares occurred?

 Flares above B, C, M, X class were      0    33     3     0

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

 Flares above B, C, M, X class were      0    26     2     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      0    12     0     0

There were RHESSI flares/GOES flares 269 / 36 over the time range 12-Nov-14 19-Nov-14

Memory Management

The SSR was emptying by the end of the daily pass set during most of the week.


As the last pass the cold tip temperatures are 106.4 K and 104.7 K. The cold plate temperatures are 127.4 and 126.1 K.

Spacecraft Operations

The spacecraft is operating nominally. The attenuators are working correctly.

Data Gaps

No data gaps this week.

Detector issues

Detector 2 continue showing light leek issues.

There were no threshold changes this week.

Other notes

Noticed some spikes in the LLD monitor rates for all detectors. Was this just bad packets?

Decimation Active/Vigorous
HLAT Decimation Rear decimation weight 6, no front decimation
Night time data (fronts) +/-4 minutes
Night time data (rears) full nighttime events
Require extra passes? No
Requirement for moving pointer? No
Attenuator operation Nominal
Detector problems? Detector 2 light leak.
