Dear Collaborators,

Solar activity is at a low level. The target region NOAA 12820 has generally
maintained spot area since the last message while developing small spots in
its interior. This region continues to be classified as a beta/D-type sunspot
group. The bipolar flux region located slightly to the West of 12820 has now
been designated as NOAA 12821 (a beta/C-type sunspot group). NOAA 12820 has
continued to produce multiple B-class events since the last message, but the
largest flare in the period was a C2.6 event on 26-Apr-2021 at 01:17 UT from
decaying NOAA 12816. The target remains as NOAA 12820 for the next 24 hours,
but observers are encouraged to include the trailing portion of 12821 in the
field-of-view if at all possible (because the trailing spot of NOAA 12821 is
moving towards the opposite polarity leading spot of NOAA 12820). Continued
B-class activity is expected in the following 24 hours, with a good chance
for a C-class flare.

The position of NOAA 12820 on 26-Apr-2021 at 22:00 UT is:

S22W18 , ( -274", -290" )
