Solar Activity

Solar activity was high in the beginning of the week and tapered off to low by the end. The sun produced 3 X-class events, with only 1 being caught by RHESSI. AR 11890, who was responsible for the X-class activity this week, is set to rotate off disk, but remains in a beta-gamma-delta configuration with a chance of producing another x-class event. The second most active region on disk, AR11897, is on the lower eastern hemisphere and has a beta-gamma configuration. Stereo-B shows an AR that will rotate on disk in a few days.

How many GOES flares occurred?

 Flares above B, C, M, X class were      1    64     8     3

Memory Management

The SSR is emptying at the end of the pass sets, and often before the last pass. We are still in Active/Vigorous mode. Rear eclipse data was turned on, and we are currently collecting data for the entire eclipse. Plus/minus 4 minutes are still on for fronts.

Spacecraft Status

Cold plate 1 is at: 117.8K. Cold plate 2 is at 116.3K.
