Dear Collaborators,

Solar activity is at a moderate level. Target region NOAA 13639 has
grown in sunspot area since the last message and been reclassified
as a beta-gamma/C-type sunspot group (due to reduced levels of limb
foreshortening). NOAA 13634 (a beta/E-type sunspot group) produced
two M-class flares in the period with the largest being an M1.4 on
15-Apr-2024 at 14:01 UT. However, target NOAA 13639 was once again
the most flare-productive region, being the source of five C-class
and four M-class flares, the largest being an M4.0 on 15-Apr-2024
at 19:25 UT. The MM#003 Major Flare Watch will continue with NOAA
13639 as the target. More low M-class flares are probable over the
following 24-hour period, with a chance for a >M5 flare.

The position of NOAA 13639 on 16-Apr-2024 at 15:00 UT is:

N30E40 , ( -534", 537" )
