Dear Collaborators,
Solar activity has slightly decreased since the last message. A number of C-class flares were produced, the largest being C8.2 at 20:46 UT yesterday from the target NOAA 13513. 13513 has now developed to a beta-gamma region with flux emergence and produced another ten C-class flares in the period. It shall remain the target region over the following 24 hours. Besides, NOAA 13511 also produced eight C-class flares during the period. Further C-class flares are expected, with a chance for low M-class flares. The position of NOAA 13513 on 8-Dec-2023 at 08:30 UT is: N18E35, (-532",301") 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.
