Severe G4 Solar Storm Triggers Tech Alerts and Mid-Latitude Auroras

BOULDER, CO – Space weather experts at NOAA confirmed that a G4 (Severe) geomagnetic storm struck Earth’s magnetosphere today, causing rare atmospheric phenomena and disrupting global communication systems.

The storm, fueled by a powerful X1.9 solar flare that erupted on January 18, has pushed auroras as far south as Death Valley and the northern United Kingdom. While the visual displays were spectacular, the storm has had real-world consequences for technology. Satellite operators have reported increased atmospheric drag, and aviation authorities warned of potential interference with GPS and high-frequency radio communications. Experts say while the storm is beginning to wane, residual effects could persist through January 21.
