Solar Activity
Solar Activity was moderate during last week. Sun has been rather quiet during last couple of days with sporadic C-class flares. Currently there are three active regions on the solar disk. Particularly the AR2321 has a high probability to host a M or X class in the next couple of days.
How many GOES flares occurred?
Flares above B, C, M, X class were 15 35 2 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 4 18 2 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 0 0 0 0
There were RHESSI flares/GOES flares 70 / 52 over the time range 07-Apr-15 14-Apr-15

We need to do a balance experiment.

Detector issues
On April 09 starting at 17:20 UTC we made a few changes to detector 6 and 8. We raised thresholds on the Front Fast D6, Front Slow D6 and Rear Fast D8.
| Threshold [G6] | Front Fast |
| Initial | 0x80 |
| Final | 0xA0 |
| Threshold [G6] | Front Slow |
| Initial | 0x0C |
| Final | 0x15 |
| Threshold [G8] | Rear Fast |
| Initial | 0x70 |
| Final | 0x80 |
On April 13 at 17:47UT we changed the Rear Fast threshold for detector 8:
| Threshold [G8] | Rear Fast |
| Initial | 0x80 |
| Final | 0x90 |
On Abril 14 starting at 14:06 UT we made the next changes on Detectors for detectors 6 and 9 that had very high values of the Front Slow valid counts.
| Threshold [G9] | Front Slow |
| Initial | 0x0C |
| Final | 0x1A |
| Threshold [G6] | Front Fast |
| Initial | 0xA0 |
| Final | 0xA8 |
| Threshold [G6] | Front Fast |
| Initial | 0xA8 |
| Final | 0xB0 |
