Dear Collaborators,

Solar activity continues at a very low level. The target region NOAA 13831 was the source of three low C-class flares (all flares during the period recorded by GOES), with the largest one being a C4.5 at 20:37 UT on September 21. 13831 retains a beta/D-type configuration. Further C-class activities are expected in the next 24 hours.

The position of NOAA 13831 on September 22 at 11:30 UT is:

N12W30 (469", 98")
