Dear Collaborators,
Solar activity is at a moderate-to-high level. Target region NOAA 13576 decayed reasonably in terms of sunspot area since the last message, but has remained classified as a beta-gamma-delta/F-type sunspot group. This region again produced several C-class flares and two M-class flares in the period - an M1.5 flare and an M1.6 flare on 12-Feb-2024 at 15:31 UT and 22:00 UT, respectively. The largest magnitude flare (an M2.7 on 12-Feb-2024 at 20:35 UT) came from a new region located at the North East limb, but an accurate classification of this region is affected by its proximity to the limb. The MM#003 Major Flare Watch will continue with NOAA 13576 for at least another 24 hours as it decays further. More M-class flares are likely in the following 24-hour period, with a chance for another >M5 flare. The position of NOAA 13576 on 13-Feb-2024 at 11:00 UT is: S17W43 , ( 636", -203" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
