Dear Collaborators, Solar activity has been at moderate levels for the past 24 hours. The largest event since the last message was an M3.1 flare at 02:45 UT today produced by a newly numbered region NOAA 13217. 13217 is rotating onto the visible disk and has been classified as a beta/D-type configuration. This region also produced two another low M-class flares (M1.5 and M1.1). It shows a high and increasing current helicity. Today the Major Flare Watch region will switch to NOAA 13217. But if possible, please also include the southeast limb region (S12E85) in your field of view, which produced an M2.9 at 08:49 UT today. Yesterday’s target region NOAA 13213 (beta-delta/E-type) produced 3 M1 flares in the period, with emerging new sunspots and new magnetic fluxes. Additional low M-class flares are expected from various regions with a chance of an above M5 flare in the next 24-48 hours. The position of NOAA 13217 on 9-Feb-2023 12:30 UT S07E65 (-876", -71") 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.
