Dear Collaborators,

The level of solar activity is low-to-moderate. Target region NOAA
13647 has again remained stable in terms of spot area and number of
spots since the last message, but has not produced any significant
flares. The majority of flares were produced by NOAA regions 13638
(a beta/C-type sunspot group) and NOAA 13645 (a beta/D-type sunspot
group) - NOAA 13638 generated three C-class flares and an M2.2 (on
21-Apr-2024 at 15:07 UT), while NOAA 13645 generated five C-class
flares and an M1.0 (on 21-Apr-2024 at 12:39 UT). At this point the
MM#003 Major Flare Watch terminates. The default target switches to
NOAA 13645 because of its more central location in the cluster of
active regions in the Southern hemisphere. More C-class activity is
expected in the next 24 hours, with a chance for low M-class flares.

The position of NOAA 13645 on 21-Apr-2024 at 15:30 UT is:

S09W27 , ( 429", -75" )
