Geomagnetic Storm Triggers Widespread Auroras, Raises Power Grid Alerts Across Northern Hemisphere
On November 15, a powerful geomagnetic storm, classified as a G3 event by the National Oceanic and Atmospheric Administration's Space Weather Prediction Center, struck Earth's magnetic field at 03:00 UTC, producing vibrant displays of the aurora borealis visible as far south as the 40th parallel in North America. The storm, caused by a coronal mass ejection from the Sun on November 13, prompted power grid operators in Canada and Scandinavia to issue voltage fluctuation warnings. Authorities advised infrastructure managers to monitor systems for potential disruptions through Thursday, while SpaceX postponed a Starlink satellite launch. The event coincided with heightened solar activity in the current solar cycle, underscoring ongoing risks to satellite and communications networks.
