|List all reports|
The Sun was active this week, producing seven M-class flares. Currently there are five AR on disk, but four of them are expected to rotate off the disk very soon.
How many GOES flares occurred?
Flares above B, C, M, X class were 39 30 7 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 21 17 5 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 12 11 2 0
There were RHESSI flares/GOES flares 188 / 76 over the time range 28-Mar-17 04-Apr-17
Early the week, the SSR was at 0% at the end of each day's contacts. In response to the high solar activities and the turn-on of some detectors, the SSR reached 75% and the decimation was switched to active/vigorous from normal/vigorous.
Detectors 3 and 6 are recording events. Due to the increased solar activities, D1, 5 and 8 were turned on. D5 was turned off soon due to its unexpectedly high event rate.
The cold tips are 129.5 and 128.0 K as of 5-Apr-2017. The cold plates, 1 and 2 are 153.3 and 151.8 K. Cryocooler power is steady at 76W. See:

Relatively large (>300 sec) data gaps as follows:

Detectors 1, 3, 6 and 8 are powered on, and are recording events.
There are counts coming in the maximum energy channel on D6. Its a "new" phenomenon, and we're not sure where its coming from or why. Don't think its damage, no high leakage current or resets. Next Tohban keep and eye on it and maybe try some tests to see where it comes from. Adjusting HV was suggested.
