Dear Collaborators,
The level of solar activity has still been high since the last message. The largest event was an X1.5 flare at 02:33 UT today from the target region between 13764 and NOAA 13766. 13764 has been classified as a beta/C-type sunspot group and 13766 (S07W03) has retained a beta/D-type configuration over the past 24 hours. Their intermediate portion with mixed polarities appears to be away from 13766 and thus closer to 13764. Today the Major Flare Watch will switch to 13764 (with NOAA 13766 in the field of view). In addition, NOAA 13762 (beta-gamma-delta/F-type, S11W49) also produced an M7.8 flare at 10:27 UT yesterday and an M8.7 flare at 12:47 UT today. Further low-M activities are expected with a good chance for additional >M5 flares in the following 24 hours. The position of NOAA 13764 at 11:30 UT on 29-Jul-2024 is: S03W13 (213", -139") 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.
