Dear Collaborators,

Solar activity has reached an intermediate due to an M1.4 at 22:47 UT on 26-Oct-2023 from an unnumbered region near North East limb (N18E80). This region was close to the recently numbered target region NOAA 13473. 13473 was now classified as a beta/B-type sunspot group and the source of 3 low-C flares. Today the target region shall still be 13473, but if possible, please include the unnumbered region (N18E80) in your field of view. Additionally, NOAA 13471 (S23W37, beta/D-type) and its nearby spotless region also produced 3 low-C flares. Further C-class flares are expected with a chance of another M-class flare in the next 24 hours.

The position of NOAA 13473 on 27-Oct-2023 at 07:30 UT is:

N13E58 (-799", 174")
