Dear Collaborators,
Solar activity has increased since the last message. The largest event was a C2.3 flare at 23:54 UT on 28-Aug-2023 produced by a northeast limb region (unnumbered yet). This region was the most flare-productive for the source of multiple low-C and B-class events. Today the target region shall switch to the limb region. Yesterday’s target NOAA 13413 (N10W32, beta-delta/D-type) only produced 3 C1 flares. NOAA 13417 (S08E68, beta/D-type) and NOAA 13416 (S19E21, alpha/H-type) also produced several C1 flares. More C-class activities are expected with a slight chance of a low M-class flare in the next 24-hour period. The approximate position of the target on 29-Aug-2023 at 11:30 UT N22E87 (-900", 350") 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.
