Dear Collaborators,

Solar activity has remained at a low level since the last message.
Yesterday's target region NOAA 13341 further decayed in terms of
sunspot area and only produced two C1 flares in the period, while
continuing to be classified as a beta/C-type sunspot group. NOAA 13340
(N23W35, beta-gamma/E-type) was the most flare-productive region
in the period with being the source of 10 C-class flares, including the
largest magnitude flare - a C7.1 at 03:49 UT today. The target will now
switch to NOAA 13340. Please note that NOAA 13337 (N21W65,
alpha/H-type) also produced a high C-class (C6.8) flare at 21:56 UT
yesterday. More C-class flares are expected over the following
24-hour period, with low M-class activity also possible.

The position of NOAA 13340 on 26-Jun-2023 at 07:30 UT is:

N23W35 (499", 341")
