Dear Collaborators,

The level of solar activity is moderate-to-high. Target NOAA 13341 has
matured since the last message without significant change in number of
spots or spot area, increasing in magnetic complexity to be classified
as a beta-gamma/D-type sunspot group. NOAA 13337, a previously decayed
region that is emerging new spots, produced an M1.0 flare in the period
(on 21-Jun-2023 at 15:31 UT) but NOAA 13341 continued to be the most
flare-productive region with being the source of several C-class flares
and the largest magnitude flare in the period - an M1.1 on 21-Jun-2023
at 12:31 UT. The MM#003 Major Flare Watch will continue on NOAA 13341.
Additional low M-class flares are probable over the following 24-hour
period, with a chance for another >M5 or X-class flare.

The position of NOAA 13341 on 21-Jun-2023 at 18:00 UT is:

S15E48 , ( -680", -264" )
