• M6.9 solar flare produces Earth-directed CME, G2 geomagnetic storm watch issued for August 28

    A strong M6.9 solar flare erupted from Active Region 4513 near the center of the visible solar disk at 10:02 UTC on August 25, 2026, causing an R2 – Moderate radio blackout. NOAA’s Space Weather Prediction Center (SWPC) said the associated CME and a second CME linked to a C4.7 flare and filament eruption later that day contained Earth-directed components, prompting a G2 – Moderate Geomagnetic Storm Watch for August 28. A G1 – Minor watch is in effect for August 27 due to an approaching coronal-hole high-speed stream.

    Solar activity reached high levels on November 5, 2025, as Region 4274 (N24E40) produced two powerful M-class flares – an M7.4 at 11:19 UTC and an M8.6 at 22:07 UTC. The full-halo CME from the first event is expected to reach Earth late November 6 to early November 7, likely producing G3 – Strong geomagnetic storm conditions and visible auroras across Canada and the northern United States.
