Dear Collaborators,

The level of solar activity is moderate. Target region NOAA 13645
grew in terms of sunspot area and number of spots since the last
message, but simplified in magnetic classification to be reported
as a beta/D-type sunspot group. Some of this decrease in magnetic
complexity is due to some of polarities observed in that location
yesterday now being identified as a new emerging sunspot region,
designated as NOAA 13647 (a beta-delta/D-type group). Multiple
C-class and three M-class flares have occurred from the vicinity
of NOAA regions 13645 and 13647, the largest being an M2.1 flare
on 19-Apr-2024 at 04:40 UT. The MM#003 Major Flare Watch remains
in effect, with a minor shift in targeting coordinates to NOAA
13647, although NOAA 13645 should be kept within an observational
field-of-view if possible. More M-class activity is expected in
the next 24 hours, with a good chance for a >M5 flare.

The position of NOAA 13647 on 19-Apr-2024 at 12:30 UT is:

S10E05 , ( -84", -80" )
