|List all reports|
Solar activity was low-moderate this week with only 10 C class flares. There are currently 7 active regions on the disk, although 4 of these will rotate over the limb within the next 36 hours. STEREO B shows a couple of active regions which will rotate onto the disk over the next few days.
How many GOES flares occurred?
Flares above B, C, M, X class were 20 10 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 14 5 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 5 3 0 0
There were RHESSI flares/GOES flares 206 / 30 over the time range 20-Feb-13 27-Feb-13
The SSR is emptying at the end of the daily pass set, with a maximum of about 25%.
Cold plate 1 and 2 temperatures are at 111 K and 110 K respectively.
The cryocooler is nominal.
There were no data gaps this week.
The front slow threshold on detector 2 was lowered on days 052 and 053 (21st and 22nd February).
The front slow valid counts were around 1200 at 0x38, a little higher than the typical ~800 seen during previous orbits. However during recent passes the counts are around ~600. The variation may be caused by orbital variation or as a result of the pass occurring while the light leak in detector 2 is present. The new tohban will keep an eye on this and will observe the situation for another week.
Note we started at 0x50 on day 052.

The detector remains unsegmented.
A spin up was carried out on the 26th February between ~17:00 UT and ~20:00UT.
