Solar Activity
Quiet...
Some GOES activity, No RHESSI flares to count.
Memory Management
Detectors were turned off for annealing at 21:35 on April 12th; Decimation was active/vigorous at the time. The SSR read pointer was moved to 135000000 on 17-April, to reduce the SSR fill to 7.5%. This resulted in a vc3 data gap from 11-apr-2018 01:50 until 16-apr-2018 02:30. Currently the SSR fill is approximately 10%.
Spacecraft Status
Detectors are off:
