Solar activity has remained at low-C levels since the last
message. NOAA 14508 (N07E20, beta/C-type) generated
the largest events being a C4.3 at 21:45 UT yesterday and
a C3.3 at 08:09 UT today. The target region NOAA 14507
has increased in spot area and number, now classified as a
beta/D-type sunspot group. This region produced a C2.1 flare
at 13:30 UT today. Moreover, NOAA 14506 (N11W24,
beta/B-type) also was the source of two ~C1 flares, with the
emergence of new magnetic fluxes. Today the target shall
continue at 14507 (with 14506 included). Further B-class
activity is expected, with a chance of additional low-C flares
in the coming 24 hours.
The position of NOAA 14507 on 15-Aug-2026 11:30 UT is:
N04W07 (115", -43")
