Dear Collaborators,
Solar activity has been at a moderate level as the target region NOAA 13363 rotates beyond the west limb. The largest event in the previous 24 hours was an occulted M2.1 flare at 20:16 UT yesterday from 13363. 13363 also produced two high C-class flares. Please note that a northeast limb region (N15E85, unnumbered yet) produced an occulted M1.5 flare at 06:45 UT yesterday and NOAA 13376 (N23E27, beta-gamma/D-type) produced two low M-class flares (an M1.3 at 19:32 UT and an M1.4 at 20:00 UT). The Major Flare Watch campaign will continue on NOAA 13363 for a final 24 hours. Low M-class activities are still expected from various regions with a slight chance of an above M5 flare in the next 24 hours. The position of NOAA 13363 on July 19 at 03:30 UT S21W88 (880", -339") 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.
