Dear Collaborators,

Solar activity is at a moderate level. Target NOAA 13340 continues to be classified as a beta-gamma/E-type sunspot group as it approaches the western limb. 13340 produced multiple C-class as well as two M1 flares in the period and the largest event was an M1.9 flare at 08:26 UT today. 13340 shall continue as the target region. Please note that NOAA 13354 (N15E07) has been classified as a beta-gamma/D-type configuration with significantly increasing in the sunspot area and number of spots. It produced nine low C-class flares during the period. More C-class flares are expected over the following 24-hour period, with a good chance for additional M-class flares from NOAA 13340 and 13354.

The position of NOAA 13340 on 28-Jun-2023 at 07:30 UT is:

N23W62 (768", 351")
