Dear Collaborators,

Solar activity is at a moderate level. Target region NOAA 13654
grew in sunspot area and number of spots since the last message,
adding penumbrae to its trailing polarity to be classified as a
beta/D-type sunspot group. This region did not produce any more
significant flares in the period. In contrast, some low M-class
flares were produced by both NOAA 13638 (a beta/B-type sunspot
group, with an M1.8 on 24-Apr-2024 at 02:30 UT) and NOAA 13645
(a beta-gamma/D-type sunspot group, with an M1.7 and an M1.4 on
24-Apr-2024 at 00:13 UT and 12:07 UT, respectively). The default
target switches back to NOAA 13645 as it rotates up to the South
West limb. Additional low M-class flares are probable over the
following 24-hour period, with a chance for a >M5 flare.

The position of NOAA 13645 on 24-Apr-2024 at 20:00 UT is:

S08W75 , ( 913", -112" )
