A powerful solar radiation storm, the strongest in over 20 years, struck Earth on January 19, triggering a severe geomagnetic storm classified as S4 and G4 by NOAA's Space Weather Prediction Center. This event has caused disruptions to satellite operations, aviation, and communication systems, while producing vivid auroras visible across much of the northern United States and parts of Canada, with sightings possible as far south as Alabama and northern California. The storm is expected to persist for several days, with impacts mainly affecting space-based technologies and high-latitude flights.
