Dear Collaborators,
Solar activity continues at low levels. The largest event since the last message was a C3.0 flare at 23:20 UT on 30-Aug-2023 from NOAA 13413. 13413 was also the source of a C1.5 flare and it retains its beta/D-type magnetic configuration. Today the target shall switch to NOAA 13413. Yesterday’s target NOAA 13417 (S05E39, beta/D-type) was quiescent in the period. In addition, NOAA 13415 (S09W38, beta/D-type) and two plage regions (S26W11, N17W49) also produced a few low-C flares. B-class activities are expected with low C-class flares probable in the next 24 hours. The position of NOAA 13413 on 31-Aug-2023 at 11:30 UT N09W55 (770", 80") 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.
