Cannibal solar storm could paint southern skies with auroras this Friday

A rare cannibal CME—a merger of an X-class flare from sunspot 4455 and following CMEs—could reach Earth this Friday, triggering a strong geomagnetic storm and lighting up auroras far farther south than usual, visible across central England and Wales and parts of the US such as Iowa, Ohio, Pennsylvania, Massachusetts, Rhode Island and New Hampshire.

Earth‑bound cannibal CME from rare anti‑Hale sunspot sparks auroras across 23 states

A cannibal coronal mass ejection from sunspot 4455—a rare anti‑Hale sunspot—is expected to slam into Earth this afternoon, likely triggering strong geomagnetic storms (G3–G4) and widespread auroras visible as far south as 23 U.S. states, with NOAA projecting mid‑afternoon arrival and skywatchers from the Pacific Northwest to the Northeast potentially seeing the lights.
