Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13311 continues to be the most complex sunspot group on the visible disk, remaining classified as a beta-gamma-delta/E-type spot group. This region maintained a high frequency of C-class flares since the last message and was also the source of the largest magnitude flare - an M3.1 on 23-May-2023 at 12:07 UT. We continue with the MM#003 Major Flare Watch targeting NOAA 13311 for another 24 hours. Additional low M-class flares are likely in the next 24 hours, with a chance for another >M5 flare.
The position of NOAA 13311 on 23-May-2023 at 18:00 UT is:
N18E10 , ( -160", 320" )
