Solar Activity
Solar activity was low this week. There are currently 5 active regions on disk. Activity is expected to remain low-moderate with a chance for an C class flares in the coming days.
How many GOES flares occurred?
Flares above B, C, M, X class were 16 13 0 0
And how many of these are listed in the RHESSI flare list?
Flares above B, C, M, X class were 10 6 0 0
And how many had EXCELLENT coverage?
Flares above B, C, M, X class were 8 2 0 0
There were RHESSI flares/GOES flares 161 / 29 over the time range 30-Jan-13 06-Feb-13
Memory Management
The SSR was emptying at the end of the daily passes during the beginning of the week. Max of around ~25%
Spacecraft Status
The cold plate 1 and 2 are at 108.5 K and 107.1 K respectively.
Data Gaps
Detector issues
On January 30 at 00:26:07 UT the high voltage of detector 2 was raised by five steps (216 -> 221). The voltage increase went smoothly, but still no segmentation. There was a very brief increase in noise, then the detector settled back to the levels we were seeing before the voltage increase.
On February 5 at 22:04:13 UT the detector 2 high voltage was raised by another five steps (221 -> 226). This increase puts G2 at 4411 V, which is now the highest voltage of all our detectors. After increasing the voltage, there was no indication of segmentation. There was also no appreciable increase in count rates or reset rates. Detector 2 still looked good on the next orbit.
