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.
A large filament eruption took place around Active Region 2987 – located at a geoeffective position – producing a C1 solar flare at 05:21 UTC on April 11, 2022. The event produced a full halo CME and WSA-Enlil model indicates arrival at Earth early on April 14. As a result, a G2 – Moderate geomagnetic…
Active Region 2975 produced multiple C- and M-class solar flares since M4.0 at 11:29 UTC on March 28, 2022, as well as 2 coronal mass ejections (CMEs) – both toward Earth. As a result, a G3 – Strong geomagnetic storm watch is in effect for March 31. Solar activity…
