Solar Activity

Solar activity this week was low with only 6 C class flares. There are currently 9 active regions on disk, several of which will rotate over the limb within the next 48 hours. STEREO B shows no bright active regions due to rotate onto the disk.

How many GOES flares occurred?

 Flares above B, C, M, X class were     13     6     0     0

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

 Flares above B, C, M, X class were      6     5     0     0

And how many had EXCELLENT coverage?

Data Gaps

There were several short data gaps (300s - 900s) between the 17th and the 19th of July.

Detector issues

On the 11th of July there was an arc in detector 7, followed by a increase in noise that can be observed in the monitor rate plots, see link below.

Detector 7's HV will be lowered by 10 steps this coming week.
