Solar Activity

Solar activity was high this week with AR 11515 producing a large number of M-class and one X-class flares. The background solar flux was at mid - high GOES C-class level. AR 11515 has now rotated off the disk and the solar background flux has dropped slightly. In the last few days AR 11520 has begun producing a number of C and M class flares. In the last 24 hours this AR has been seen to decay slightly and has been down graded from a beta-gamma-delta configuration to a beta-gamma. However a Major Flare Watch is still in place for this region with the chance of further M-class flares.

How many GOES flares occurred?

 Flares above B, C, M, X class were      0    65    31     1

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

 Flares above B, C, M, X class were      0    45    19     0

And how many had EXCELLENT coverage?

 Flares above B, C, M, X class were      0    23     9     0

There were RHESSI flares/GOES flares 402 / 97 over the time range 04-Jul-12 11-Jul-12

Memory Management

Due to the increased solar activity a number of extra WHM and WLPS passes were scheduled to download the data. The SSR reached a max of XXX. Currently the SSR is around 20%.

Spacecraft Status

Cold plate 1 and 2 are currently sitting at 106 and 105 K respectively. This is partially due to the current day length, however in general the temperature is slowly increasing.

Data Gaps

There were no data gaps this week.

Detector issues

Detector 8 is starting to look a little noisy coming out of the SAA, something to keep an eye on.
