Dear Collaborators,
The level of solar activity has increased since the last message. NOAA 14503 (S17W60, beta/C-type) produced the largest flare, a C4.1 at 06:38 UT today. NOAA 14507 has continued to develop and is now classified as a beta-gamma/D-type. It has produced seven mid-to-high B-class flares. Today the target will switch back to 14507. Yesterday’s target has been designated NOAA 14511, but it remained flare-quiet during the period. Further B-class activity is expected, with a chance of low-C flares in the next 24 hours.
The position of NOAA 14507 on 14-Aug-2026 11:30 UT is:
N04E08 (-132", -42")
