Dear Collaborators,
Solar activity is at a moderate level. Target region NOAA 13639 has grown in sunspot area since the last message and been reclassified as a beta-gamma/C-type sunspot group (due to reduced levels of limb foreshortening). NOAA 13634 (a beta/E-type sunspot group) produced two M-class flares in the period with the largest being an M1.4 on 15-Apr-2024 at 14:01 UT. However, target NOAA 13639 was once again the most flare-productive region, being the source of five C-class and four M-class flares, the largest being an M4.0 on 15-Apr-2024 at 19:25 UT. The MM#003 Major Flare Watch will continue with NOAA 13639 as the target. More low M-class flares are probable over the following 24-hour period, with a chance for a >M5 flare. The position of NOAA 13639 on 16-Apr-2024 at 15:00 UT is: N30E40 , ( -534", 537" ) 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.
