Solar Activity

Solar activity actually has turned on; the new AR2706 has grown a pretty big spot formation but has not made even a C-class flare yet.

Memory Management

Current SSR fill is over 29%. Decimation has been Active/Vigorous all week.

Spacecraft Status

We are still annealing. Annealing started at 21:35 on April 12th and still in progress.

All detectors are off.

for a summary plot of recent temperatures, efficiencies and accelerometer values.

Sunday Abril 29 at 10 pm we plan to start to cool down.

Data Gaps

Some data gaps between April 21st and April 24th.
