Dear Collaborators,
Solar activity has decreased to a moderate level. The target region NOAA 14100 was the source of an M4.5 at 08:08 UT and an M2.9 at 15:36 UT flares yesterday. This region has developed a delta to beta-gamma-delta/E-type sunspot group. Today, the Major Flare Watch will remain in effect with NOAA 14100. More low-M activity is probable, with a chance for an isolated >M5 flare in the following 24 hours.
The position of NOAA 14100 on 1-Jun-2025 at 11:30 UT is:
N08W07 (114", 142")
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.
