Dear Collaborators,
Solar activity has diminished since the last message. The largest event during the period was a C4.8 flare at 17:01 UT yesterday, attributed to NOAA 13538. This region is now full behind the northwest limb. The target region NOAA 13539 produced three ~C3 flares in the period, which shall remain as the target region for an additional 24 hours. Further C-level activity likely with a slight chance for an isolated low M-class flare. The position of NOAA 13539 on 13-Jan-2024 at 12:30 UT is: N10W76, (932",186") 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.
