Dear Collaborators,
Solar activity is at a low-to-intermediate level. Yesterday's target NOAA 13450 (S19E39) only produced a C1.9 flare in the period, although it was classified as a beta-gamma/E-type sunspot region. A newly emerged region (unnumbered yet) near the North East limb was the most flare-productive region with being the source of ten C-class flares, including two ~C7 flares that erupted at 09/29/18:11 UT and 09/30/03:57 UT respectively. This region continues to undergo flux emergence and shall be the new target. Besides, NOAA 13445 (S14W69, beta/C-type) also produced four C-class flares, including the largest magnitude flare in the period - a C8.0 at 09/30/05:56 UT, but showing signs of decay. Further C-class flares are expected over the next 24-hour period, with a slight chance of low M-class activities.
The approximate position of the target on 30-Aug-2023 at 11:00 UT is:
N11E68 (-760", 150")
