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?
Flares above B, C, M, X class were 5 1 0 0
There were RHESSI flares/GOES flares 121 / 19 over the time range 17-Jul-13 24-Jul-13

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.
