Dear Collaborators,
Solar activity is at an extremely low level. The target region was confirmed as being numbered as NOAA 12843 at the beginning of the UT day, but at that time it had decreased in complexity to be classified as an alpha/A-type sunspot group. Although the two flares that occurred from NOAA 12843 since the last message included the largest of the period (a B5.3 event on 15-Jul-2021 at 18:44 UT), a succession of low B-class flares were produced by a new sunspot region while rotating over the South East limb. This new region has not yet fully rotated on disk, but becomes the target because further B-class flares are probable from it in the following 24-hour period.
The approximate position of this region on 15-Jul-2021 at 20:30 UT is:
S45E84 , ( -664", -671" )
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.
