Dear Collaborators,
The level of solar activity is moderate. Target region NOAA 13354 has remained a beta-gamma-delta/E-type configuration and increased in size since the last message, showing mixed polarities in its intermediate and northern portions. 13354 was the most flare-productive region in the period with being the source of several C-class flares, including the largest magnitude flare - an M3.8 at 14:00 UT yesterday. 13354 shall continue as the target region due to its high current helicity and magnetic complexity. More C-class flares are expected over the following 24-hour period, with a good chance for additional M-class flares.
The position of NOAA 13354 on 30-Jun-2023 at 07:30 UT is:
N15W20 (312", 203")
