Dear Collaborators,
Solar activity has increased to a moderate level. Yesterday's target rotated from the Southeast limb produced two M class flares since the last message: a M1.0 at 14:54 UT yesterday(6/20) and a M2.6 at 2:25 UT today, the latter was the largest event in the period. This region, now assigned to NOAA 14473, is also the source of several high-B to mid-C class events in the last 24 hours. The leading (Western) portion of this region consists of multiple small spots with mixed polarity, while the Eastern portion appears to be a single large spot with negative polarity (still too close to the limb to describe further).
Today, we will continue to observe NOAA 14473 at the leading portion of sunspots where the M2.6 flares are from. Additional C class to low-M class events are expected.
The position of the target in NOAA 14473 on 21-Jun-2026 at 15:30 UT is: S08E57 (-790.", -155").
