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

Memory Management

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
