Dear Collaborators,
Solar activity has grown to an intermediate level since the last message. Several >C5 flares are produced from NOAAs 14204, 14199, 14195, and 14203. 14204 (alpha/H-type, N03E50), 14199 (beta/C-type, N04E38), and NOAA 14195 (alpha/A-type, S18E07) produced a C9.3 flare (the largest in the period) at 12:27 UT yesterday, a C5.4 at 14:24 UT yesterday, and a C6.6 flare at 00:06 UT today, respectively. Two ~C5 flares at 00:26 UT and at 11:25 UT today were produced by 14203. This region has been the most productive and has increased in magnetic complexity to be classified as a beta/D-type. Today, the target shall switch to NOAA 14203 from NOAA 14197. Yesterday's target 14197 (beta-gamma/E-type, S17E23) only produced three low-C flares. Further C-class activity is expected, with an isolated low-M flare likely in the following 24 hours.
The position of NOAA 14203 on 27-Aug-2025 at 11:30 UT is:
N12W82 (920", 179")
