A rare and powerful solar event lit up skies across the globe on Jan. 19, 2026, as a severe G4-class geomagnetic storm produced one of the most widespread displays of the Northern Lights in recent memory.
The spectacle was triggered by a fast-moving coronal mass ejection that struck Earth’s magnetic field much earlier than predicted at around 19:30 UTC, catching forecasters by surprise.
The timing of its arrival allowed for immediate aurora sightings across Europe, with reds and greens seen across China, Scandinavia, the U.K. and across Europe, from Germany and France to Hungary. Although it was a strong enough display to have been seen as far south as Arizona, Texas and southern California, geomagnetic activity had slowed by the time darkness fell across North America.
