Dear Collaborators,
Solar activity is at a low-to-moderate level. Yesterday's target NOAA 13500 only produced one B9 and two low C-class flares during its approach to the South West limb. The largest event in the period was a C8.1 flare at 01:22 UT today, produced by a newly emerged active region NOAA 13511 (S23E16, beta/B-type), which was also the source of another two ~C1 flares. 13511 continues to undergo flux emergence and shall be the new default target region. There is a possibility of high C-/low M-level activity over the next 24 hours. Also include the nearby NOAA 13510 (S15E15, beta/C-type) in your field of view if possible, which also produced two C1 flares in the period. The position of NOAA 13511 on 4-Dec-2023 at 12:30 UT is: S23E16, (-247",-389") 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)
