Dear Collaborators,
Solar activity is at a low level. Target region NOAA 13576 slowed in decay since the last message, increasing again in longitudinal extent to become classified as a beta-gamma-delta/F-type sunspot group. This region continues to be the source of almost all the flares in the period, having produced multiple C-class flares and the largest magnitude event (a C7.5 on 14-Feb-2024 at 17:53 UT). At this point we terminate the MM#003 Major Flare Watch because the delta-spot in NOAA 13576 has weakened. Further C-class flares are expected over the following 24-hour period, with a chance for an M-class flare.
The position of NOAA 13576 on 15-Feb-2024 at 12:30 UT is:
S16W72 , ( 888", -232" )
