Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13341 again remained stable in terms of sunspot area and number of spots since the last message, but has shown some signs of spot separation while continuing to be classed as a beta/C-type sunspot group. NOAA 13335 (a beta/E-type region) was the most flare-productive region in the period (at least in terms of flare frequency) with being the source of multiple C-class flares, but NOAA 13341 still produced a few C-class flares and the largest magnitude flare - an M4.8 flare on 22-Jun-2023 at 23:29 UT. The MM#003 Major Flare Watch remains in effect on NOAA 13341 for another 24 hours. Low M-class flares are probable over the following 24-hour period, with a chance for a >M5 or X-class flare. The position of NOAA 13341 on 23-Jun-2023 at 18:00 UT is: S16E25 , ( -387", -290" ) 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.
