Dear Collaborators,

The level of solar activity is moderate. Target region NOAA 13645
remained stable in sunspot area and number of spots since the last
message, continuing in classification as a beta-gamma/D-type spot
group. This region was one of three to produce low M-class flares
in the period (an M1.0 on 25-Apr-2024 at 01:40 UT) with the other
NOAA regions being 13647 (a beta/D-type spot group, with an M1.1
on 24-Apr-2024 at 22:27 UT) and 13638 (a beta/C-type spot group,
with an M2.0 on 24-Apr-2024 at 22:54 UT and M1.0 on 25-Apr-2024 at
13:11 UT). The default target will remain as NOAA 13645, but their
close proximity to each other and strong foreshortening effects
with being near the South West limb may allow observers to include
NOAA 13645 and one or both of these other two regions within their
field-of-view. More low M-class activity is probable in the next
24 hours, with a chance for a >M5 flare.

The position of NOAA 13645 on 25-Apr-2024 at 16:00 UT is:

S08W80 , ( 930", -119" )
