Moderate M1.7 solar flare erupts at 19:36 UTC on August 24, 2026

A moderate M1.7 solar flare erupted at 19:36 UTC on August 24, 2026.

Today’s flares include a B9.3 flare from region 4513 at its peak at 02:23 UTC, and a C2.2 flare from region 4513 peaking at 07:23 UTC. Additional flare events were observed from regions 4513 and 4516 throughout the day, though no M- or X-class flares are listed in the available solar event records for August 24, 2026.

In 24 hours to 12:30 UTC on August 24, solar activity was at low levels. Multiple low-level C-class flares occurred, with the largest being a C3.5 event. No Earth-directed CMEs were detected.

Solar activity is expected to be at low levels, with a chance for M-class flares and a slight chance for an X-class flare during August 24 to 26.

Active sunspot regions presently observed on the Earth-facing solar disk include AR 4513 (N04E25 – Beta-Gamma), AR 4514 (S10W99 – Alpha), AR 4515 (S07E36 – Alpha), AR 4516 (N17W44 – Beta), and AR 4517 (N10E11 – Beta).

Over the past 24 hours, the greater than 2 MeV electron flux reached high levels, while the greater than 10 MeV proton flux remained elevated but below S1 – Minor storm thresholds. The electron flux is forecast to remain high through August 26, with a chance for S1-level proton flux on August 24 and a slight chance on August 25 and 26.

The solar wind environment remained at background levels, with total magnetic field strengths at or below 5 nT. Solar wind speeds were 365-440 km/s. No significant periods of southward Bz were observed. Background solar wind conditions are expected to prevail through August 26.

The geomagnetic field was at quiet levels under ambient solar wind conditions. Geomagnetic activity is expected to remain mostly quiet through August 26.
