Dear Collaborators,

Solar activity is at a moderate level. Target region NOAA 13645 has
emerged some magnetic flux since the last message, increasing in
sunspot area and number of spots. As a result, this region changed
in classification to be a beta-gamma/D-type group. NOAA 13645 was
the source of two M-class flares in the period (an M1.0 and an M1.6
on 22-Apr-2024 at 07:59 UT and 13:13 UT, respectively), while the
largest magnitude flare was an M3.4 on 21-Apr-2024 at 21:44 UT from
NOAA 13638 (beta/C-type group located close to NOAA regions 13645
and 13647). The default target continues as NOAA 13645 for the next
24 hours due to being larger with more complex sunspot structure.
However, all regions in this Southern-hemisphere complex are being
monitored for their evolution and a possible upgrading to a MM#003
Major Flare Watch. Further low M-class activity is probable over
the following 24-hour period, with a chance for a >M5 flare.

The position of NOAA 13645 on 22-Apr-2024 at 16:00 UT is:

S09W43 , ( 643", -89" )
