Moderate M1.0 solar flare erupts at 06:45 UTC on April 27, 2026

A moderate M1.0 solar flare erupted at 06:45 UTC on April 27, 2026.

Today’s flares include several C-class events with C2.7 beginning at 00:58 UTC, C3.3 beginning at 01:07 UTC, C4.6 beginning at 01:28 UTC, C6.8 beginning at 01:53 UTC, and C6.5 beginning at 02:09 UTC. No M-class or X-class flare is listed as peaking at 06:45 UTC in the available dataset.

In 24 hours to 00:30 UTC on April 27, solar activity was at moderate levels with several M-class and C-class flares reported.

Moderate solar activity is likely, with a slight chance for X-class flares, through April 29 due to the complexity of active regions.

Over the past 24 hours, greater than 2 MeV electron flux was at low to moderate levels, peaking at 573 pfu, while proton flux remained at background levels. High electron flux levels are anticipated on April 27, expected to return to moderate from April 28 to 29. Proton levels are forecast to remain at background over this period.

Solar wind was elevated, averaging 455 km/s, with total magnetic field peaking at 14.5 nT. Variability was observed in the north-south component. Further enhancements are expected on April 27, returning to near-background by April 28, with possible increases late on April 29.

The geomagnetic field was quiet to active. Active periods are likely on April 27 before mostly quiet conditions return, with isolated unsettled levels expected April 28 and possible increases late on April 29.
