A major solar flare measuring X1.3 erupted from newly numbered Active Region 4482 on the southeast limb at 20:41 UTC on July 4, 2026. A coronal mass ejection (CME) was produced, but due to the location of the source region, an Earth-directed component is unlikely.
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.
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.
A moderately strong solar flare measuring M5.7 at its peak erupted from Active Region 4436 at 13:39 UTC on May 10, 2026. The event started at 13:19 and ended at 14:02 UTC.
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.
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.
A moderately strong solar flare measuring M2.7 erupted from Active Region 4392 at 12:15 UTC on March 16, 2026. The event lasted 24 minutes.
An impulsive X4.2 solar flare erupted from geoeffective Active Region 4366 at 12:13 UTC on February 4, 2026. The flare originated from a magnetically complex beta-gamma-delta region that produced dozens of M- and 5 other X-class flares since February 1. Its location near the central solar disk raises the possibility of Earth-directed coronal mass ejections (CMEs) this week.
An X1.5 solar flare erupted from AR 4366 at 14:08 UTC on February 3, 2026, the fifth X-class event recorded since February 1. The flare caused an R3-level radio blackout over daylight regions of Earth, affecting HF communication across the Atlantic and parts of Europe and Africa.
A long-duration X1.9 solar flare erupted from Active Region 4341 at 18:09 UTC on January 18, 2026. The event began at 17:27 and ended at 18:51 UTC. Coronagraph imagery indicates that a full halo coronal mass ejection (CME) was produced during the eruption. Given the location of the source region on the solar disk, the CME is considered likely to be at least partially Earth-directed, pending further analysis of its speed and magnetic structure.
