Solar Activity
Solar activity during the week continue at low levels. Currently there are three active regions on disk. There is a large coronal hole on disk. Solar activity is expected to be very low with a slight chance for C-class flares for the forecast period (01 - 03 Feb).
How many GOES flares occurred?
Flares above B, C, M, X class were 22 1 0 0
RHESSI flare list contains 0 over the time range 25-Jan-17 01-Feb-17
No overlapping RHESSI flares to count, sorry
Memory Management
The SSR reached a maximum of ~30 percent during the week.
Spacecraft Status
Detectors 3 and 6 are active and taking data. The cold plate 1 and 2 temperatures are ~149.9K and 148.4K.
Currently the Cryocooler power is ~75.6 W and the acceleration is at ~11mg

Detector issues
On January 26 detector 1 was turned off and detector 6 was turned on. Detector 6 segmented at about 3000V showing one count in the rear slow valids. On January 27 the detector voltage was increased to 3500V and a series of threshold changes were made.
