Dear Collaborators,

Solar activity has been at a moderate-to-low level since the
last message. Yesterday's target region NOAA 13340 retained
a beta-gamma/E-type configuration and only produced two C1
flares in the period. It continues to decay. The largest event in
the period was a C5.5 flare from NOAA 13354 (N14W07) at
18:33 UT yesterday. 13354 remained as the largest sunspot group
on the visible disk, which has increased in magnetic complexity
and been classified as a beta-gamma-delta/E-type configuration
with minor mixed polarities within its intermediate portion. Today
the target shall switch to NOAA 13354. Please note that the nearby
region NOAA 13351 (N21W12, beta/B-type) also produced a C5.0
flare in the period. If possible, please also include NOAA 13351 in
your field of view. Further C-level flares are expected in the following
24 hours, with a chance for an isolated M-class flare.

The position of NOAA 13354 on 29-Jun-2023 at 07:30 UT is:

N14W07 (112", 187")
