List all reports


Solar Activity

Solar activity this week was moderate. A Major Flare watch was called for AR NOAA 12222 which produced 4 M class flares before rotating off the disk a few days ago. There are currently 8 active regions on disk, the most active of which is AR 12230, which has produced a number of C class flares in the last 24 hours and is currently located in the center of the disk.

Memory Management

Currently the SSR is not emptying at the end of each daily pass set, due to the increased solar activity and the collection of front data during eclipse. However the SSR fill level is starting to trend downwards.


Cold plate temperatures are at 125.5 K and 124.1 K.
