Dear Collaborators,
Solar activity has been at a high-to-intermediate level. The largest event since the last message was an M6.4 flare at 19:40 UT from an unnumbered region near the South East limb (S25E70). This region also produced an M4.3 flare at 14:04 UT yesterday. The target region NOAA 13764 has decayed slightly in sunspot area and number of spots and was confirmed as an alpha/H-type configuration, while NOAA 13766 (S07W18) emerged new spots to be classified as a beta-gamma-delta/E-type region. This close pair of NOAA regions only produced two M1 flares in the period. Today the Major Flare Watch region will continue as NOAA 13764 due to its past >M5 activities and proximity to NOAA 13766. Further low-M activities are expected with a good chance for additional >M5 flares from various regions in the following 24 hours. The position of NOAA 13764 at 11:30 UT on 30-Jul-2024 is: S03W26 (415", -133") 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. Regards, Qiao Li (Purple Mountain Observatory)
