Dear Collaborators,

The level of solar activity low-to-moderate. Target region NOAA 13639
grew in sunspot area and number of spots since the last message, and
has now been reclassified as a beta-gamma-delta/E-type sunspot group.
NOAA regions 13639 and 13634 (now a beta/D-type sunspot group) have
both reduced in peak flaring magnitude, with only a C2.3 flare from
NOAA 13634 (on 17-Apr-2024 at 04:43 UT) and nine C-class flares from
NOAA 13639, with the largest being a C8.1 on 17-Apr-2024 at 03:13 UT.
The largest magnitude flare in the period was an M1.1 from NOAA 13637
(a beta-delta/D-type sunspot group) on 16-Apr-2024 at 17:49 UT. The
MM#003 Major Flare Watch will continue with NOAA 13639 as the target
for another 24 hours. Further low M-class flares are possible in the
next 24 hours, with a chance for an isolated >M5 flare.

The position of NOAA 13639 on 17-Apr-2024 at 15:00 UT is:

N29E28 , ( -394", 532" )
