• Major X1.0 flare erupts from Region 4366, Earth-directed CMEs possible in days ahead

    ByTeo Blašković

    A major X1.0 solar flare erupted at 12:33 UTC on February 1, 2026, from Active Region 4366, following a sequence of strong M-class flares earlier in the day, including M6.6 and M6.7 flares within two hours. The event started at 11:52 and ended at 12:38 UTC. With the region now rotating toward the center of the solar disk and maintaining a complex beta-gamma-delta magnetic configuration, conditions are favorable for Earth-directed CMEs in the days ahead.

  • Rare auroral glow detected within South Atlantic Anomaly during January 19 severe geomagnetic storm

    Severe geomagnetic storm on January 19, 2026, generated a rare auroral glow inside the South Atlantic Anomaly, a region where Earth’s magnetic field is significantly weaker. Photographers in Brazil captured a diffuse purple band over Cambará do Sul during peak geomagnetic activity, documenting the latest in rare instances of possible auroral or SAR arc activity within the anomaly.

  • CME impact forecast early January 20 with G4 – Severe or higher storm risk and aurora as low as California

    ByTeo Blašković

    A G4 – Severe or greater geomagnetic storm is forecast for early January 20, 2026, as a full-halo coronal mass ejection from the January 18 X1.9 solar flare approaches Earth. If G4 conditions materialize, auroral activity is expected to expand significantly equatorward, with visibility possible as far south as Alabama and northern California.

  • Long-duration X1.9 solar flare erupts from Region 4341, Earth-directed CME produced

    ByTeo Blašković

    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.

  • CME and coronal hole influences cause G1-G2 geomagnetic storming, M3.3 flare erupts beyond solar limb

    ByTeo Blašković

    A long-duration M3.3 flare erupted from just beyond the east-southeast limb at 11:00 UTC on January 11, 2026, as CME and coronal hole influences continued to disturb the solar wind environment. The geomagnetic field reached G1 – Minor to G2 – Moderate storm levels on January 10–11 under combined CME and coronal hole high-speed stream effects. Elevated solar wind parameters and unsettled-to-active geomagnetic conditions are expected to persist through January 14.

  • Multiple Earth-directed CMEs expected to trigger G1 geomagnetic storm and aurora at high latitudes

    ByTeo Blašković

    Multiple coronal mass ejections (CMEs) launched from Active Region 4334 on January 8, 2026, are expected to deliver a glancing blow to Earth between late January 10 and early January 11, according to the U.S. Space Weather Prediction Center (SWPC). The interaction of several CMEs and a coronal hole high-speed stream is forecast to cause isolated G1 – Minor geomagnetic storm conditions. Aurora may become visible across high latitudes, including the northern tier of the United States, such as northern Michigan and Maine.
