• M6.8 solar flare erupts from Active Region 4473

    A strong M6.8 solar flare erupted from Active Region 4473 on June 21, 2026, becoming the strongest flare produced by the region so far and the strongest since X1.0 on June 3. The event began at 19:17 UTC, reached maximum intensity at 19:29 UTC, and ended at 19:35 UTC.

  • X1.0 solar flare erupts from geoeffective Region 4455

    An X1.0 solar flare erupted from Active Region 4455 at 11:28 UTC on June 3, 2026, producing R3 – Strong radio blackout conditions on the sunlit side of Earth. This is the third major flare from the same region today, following M9.3 at 01:36 UTC and M7.7 at 07:00 UTC.

  • M9.3 and M7.7 solar flares erupt from AR 4455, launching Earth-directed CMEs

    A strong solar flare measuring M9.3 at its peak erupted from Active Region 4455 at 01:36 UTC on June 3, 2026, producing an Earth-directed coronal mass ejection (CME). The event started at 01:22 UTC and ended at 01:43 UTC. At 07:00 UTC, another strong solar flare — M7.7 — erupted from the same region and produced another Earth-directed CME.

  • M-class flare risk remains high from Regions 4420 and 4425 through April 29

    Solar activity reached high levels on April 26, 2026, after Region 4420 produced an M6.0 flare at 22:57 UTC, reaching R2 – Moderate radio blackout level. NOAA’s Space Weather Prediction Center (SWPC) forecasts a 70% chance of additional M-class flares capable of R1–R2 radio blackouts and a 25% chance of X-class flares capable of R3 or greater events through April 29.

  • X2.5 solar flare erupts at 08:13 UTC, second X-class event of April 24

    An X2.5 solar flare erupted from Active Region 4419 at 08:13 UTC on April 24, 2026, marking the second X-class event within hours after an earlier X2.4 flare at 01:07 UTC. The event started at 08:01 UTC and ended at 08:18 UTC. The flare produced strong radio emissions and reached R3 (Strong) radio blackout levels on the sunlit side of Earth.

  • Major X2.4 solar flare erupts near Sun’s west limb

    A major X2.4 solar flare erupted from Active Region 4419 at 01:07 UTC on April 24, 2026. The event started at 00:51 UTC and ended at 01:13 UTC. A large coronal mass ejection was produced, but it’s not expected to be Earth-directed. This is the first X-class solar flare since X1.4 on March 30.
