Dear Collaborators,
Solar activity has slightly increased to a mid-C level since the last message. The largest event was a C5.8 flare at 12:56 UT on 07-Dec-2022 produced by NOAA 13157 that was classified as a beta/C-type region. 13157 also produced five low C-class and three high B-class activities in the period. Today the target shall switch to NOAA 13157. Yesterday's target NOAA 13158 (N24W29) was flare quiet during the period and has decayed to a beta/C-type configuration. The recently emerged regions in the northeast quadrant, designated as NOAA 13159 and 13160, have been classified as alpha/A-type and alpha/H-type configurations respectively. Further C-level activities are likely over the next 24 hours with a chance for a low M-class flare. The position of NOAA 13157 on 07-Dec-2022 at 16:30 UT is: N17E23 (-365", 284") 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.
