Dear Collaborators,
Yesterday's Target NOAA 13738 just produced an X1.9 flare (at 13:11 UT) when it was rotating over the west limb. This region retains a complex beta-gamma-delta/F-type configuration though it seems to enter the decay phase. The Major-Flare-Watch target will switch back to 13738 for the next 24 hours. M-class activities are expected with a chance of a major (>M5) flare (perhaps occulted) in the following 24-hour period. The position of NOAA 13738 on July 16 at 11:30 UT is: S09W75 (901", -166") 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.
