Solar Activity

Solar activity was very low this week. There are currently 2 ARs on the disk with the probability of some C class flares in the following days.

How many GOES flares occurred?

 Flares above B, C, M, X class were      5     2     0     0

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

 Flares above B, C, M, X class were      3     2     0     0

And how many had EXCELLENT coverage?

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

There were RHESSI flares/GOES flares 45 / 7 over the time range 15-Jul-15 22-Jul-15

Memory Management

The SSR fill level reached a maximum of ~23 and a minimum of about ~17 during the week.

Spacecraft Status

The cold plate 1 and 2 are at about 133.8 K and 132.0 K respectively.

Detector issues

Light leaks visible in the flux of detector 2

In 15 July 2015 detector 4 front slow threshold was change from 0x70 to 0xA0 to see if the count flux change. The counts rate during the pass did not change appreciably. Because of that the threshold was changed to the original 0x70.

The rear fast threshold of detectors 1,6 and 7 was change on 22 July 2015 to improve their livetimes.
