Moderate M1.3 solar flare erupts at 00:23 UTC on April 26, 2026

A moderate M1.3 solar flare erupted at 00:23 UTC on April 26, 2026.

Today’s flares include an M1.3 flare and an M1.1 flare on April 25, with no X-class events or further flares currently reported for April 26, 2026.

In 24 hours to 00:30 UTC on April 26, solar activity was at moderate levels. The largest events were an M1.3 flare and an M1.1 flare, accompanied by several isolated C-class flares.

Solar activity is expected to be at low levels, with further M-class flares likely and a chance for X-class flares through April 28, mostly related 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 4421 (S11E24 – Alpha), AR 4422 (N08W73 – Alpha), 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 was at low to moderate levels, while the greater than 10 MeV proton flux remained slightly elevated but near background levels. Electron flux is expected to be at moderate to high levels through April 28, while proton flux should remain at background values with a decreasing chance of S1 – Minor solar radiation storms.

Solar wind parameters were marginally enhanced, with speeds declining from 450 km/s to 350 km/s, but trending upward again late in the period. Magnetic field strength peaked at 12 nT with a southward Bz of -9 nT and solar wind speeds returning to 450 km/s, reflecting a possible glancing influence from previous CMEs. Further enhancements in solar wind are anticipated April 26–27 due to additional glancing CME effects.

The geomagnetic field was quiet to unsettled in the past day. Isolated G1 – Minor geomagnetic storm conditions are possible late on April 26, followed by quiet to unsettled activity as CME influences subside.
