Geomagnetic Storm Disrupts Satellite Communications Across Northern Hemisphere
WASHINGTON, D.C. — A severe geomagnetic storm, classified as a G4 event by the National Oceanic and Atmospheric Administration, struck the Earth’s magnetosphere at 14:00 UTC, causing widespread disruption to satellite communications and power grid operations across the Northern Hemisphere, officials confirmed Wednesday.
The storm originated from a coronal mass ejection from the Sun, detected by the Solar and Heliospheric Observatory earlier this week. Authorities reported intermittent radio blackouts affecting aviation and maritime navigation in high-latitude regions, including Canada, Scandinavia, and northern parts of the United States.
Power grid operators in affected areas issued alerts to mitigate potential voltage fluctuations, while satellite operators temporarily adjusted orbital positions to protect sensitive electronics. Spectacular aurora borealis displays were reported as far south as Oregon and New York, with some observers noting visible activity in the Midwest.
The event caused no reported casualties, but emergency management agencies advised residents to maintain backup communication systems. Scientists from the Space Weather Prediction Center continue to monitor the storm’s intensity, forecasting possible residual effects over the next 48 hours.
