Dear Collaborators,
Solar activity is at a low-to-moderate level. Target region NOAA 13647 Has remained stable in terms of sunspot area and number of spots since the last message, but has increased in primary spot separation while remaining classified as a beta/D-type sunspot group. This region has decreased in flaring activity, producing only a C2.5 on 20-Apr-2024 at 04:38 UT in the period. The most flaring region was instead NOAA 13638 (a beta/C-type sunspot group) that is located extremely close to NOAA 13647 (and 13645). NOAA 13638 produced eight C-class flares, the largest of which was a C4.8 on 20-Apr-2024 at 00:57 UT (also the largest in the period). The MM#003 Major Flare Watch will continue for a possibly final 24 hours. Further C-class flares are expected over the following 24-hour period, with a chance for M-class flares. The position of NOAA 13647 on 20-Apr-2024 at 15:30 UT is: S13W09 , ( 146", -132" ) 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.
