Moderate M1.3 solar flare erupts at 07:59 UTC on April 25, 2026

A moderate M1.3 solar flare erupted at 07:59 UTC on April 25, 2026.

Today’s flares include an X2.4 flare at 01:07 UTC, an X2.5 flare at 08:13 UTC, and an M6.4 flare at 18:15 UTC, all on April 24, 2026. No event reports are present for April 25, 2026, as of 08:07 UTC.

In 24 hours to 00:30 UTC on April 25, solar activity reached high levels. The primary events were an X2.4 flare at 01:07 UTC, an X2.5 flare at 08:13 UTC, and an M6.4 flare at 18:15 UTC on April 24, 2026. Seven numbered sunspot regions are currently on the visible disk, with several eruptions resulting in CMEs that are mostly modeled to pass ahead and above Earth with only slight glancing effects.

Solar activity is expected to be at moderate (R1-R2 – Moderate) levels through April 26, with a chance for X-class (R3 – Strong or greater) flares due to complex sunspot regions.

Active sunspot regions presently observed on the Earth-facing solar disk include AR 4419 (N15W79 – Beta-Gamma-Delta), AR 4420 (N17E10 – Beta-Gamma-Delta), AR 4423 (S05E30 – Beta-Delta), AR 4424 (N17E45 – Beta), and AR 4425 (N06E76 – Beta).

Over the past 24 hours, the greater than 2 MeV electron flux at geosynchronous orbit reached high levels with a peak of 5 740 pfu, and the greater than 10 MeV proton flux remained at background. The greater than 2 MeV electron flux is expected to be at moderate to high levels through April 27. There is a chance for levels to exceed S1 – Minor thresholds due to continued flare activity.

Solar wind parameters reflected near background conditions. The total magnetic field averaged about 4 nT and reached a peak of 7.0 nT late in the period. Solar wind speeds were between 350 and 425 km/s. Mild enhancements are possible on April 25 due to a possible +CH HSS, with further enhancements possible on April 25–26 from glancing CMEs.

The geomagnetic field was mostly quiet with two isolated unsettled periods during the past 24 hours. The geomagnetic field is expected to be mostly quiet to unsettled on April 25, with isolated G1 – Minor to G2 – Moderate storm conditions possible late on April 25 into early April 26 due to CME arrivals, then returning to quiet to unsettled as influences subside.
