Dear Collaborators,
Solar activity had been moderately high since the last message. Yesterday's target NOAA 13513 retains its beta-gamma magnetic configuration and produced a small number of low C-class flares in the period, while NOAA 13511 (a beta/E-type) was the source of three M-class plus more than ten C-class flares, including the largest in the period - an M5.4 flare at 22:57 UT yesterday. At this time we are implementing a Major Flare Watch campaign with NOAA 13511 as the new target region due to the complexity of the magnetic field connection between it and the nearby active regions (such as NOAA 13510) and its additional flux emergence. Further low M-class activities are expected in the following 24-48 hours, with a chance for another above M5 flare. The position of NOAA 13511 on 9-Dec-2023 at 12:30 UT is: S22W52, (713",-364") 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. Regards, De-Chao Song (Purple Mountain Observatory)
