Geomagnetic Storm Disrupts Communications and Illuminates Skies Worldwide
WASHINGTON, D.C. (March 21, 2025) — A severe geomagnetic storm struck the Earth’s atmosphere late Thursday evening, causing temporary disruptions to satellite communications and power grids while producing vivid aurora displays visible as far south as Texas and Florida. The National Oceanic and Atmospheric Administration reported the storm reached G4 intensity, the second-highest level on its scale, prompting warnings for infrastructure operators and aviation authorities. Coronal mass ejections from a solar flare earlier this week triggered the event, leading to GPS navigation errors and brief radio blackouts over polar regions. Officials advised the public to expect continued interference through Friday morning, with skywatchers across 30 states capturing rare pink and green light shows. No injuries or significant damage have been reported.
