Severe Solar Storm Promises Northern Lights, with Satellite and GPS Disruptions Possible

Earth is bracing for a powerful solar radiation storm (S4), the largest in over two decades, which could spark vivid auroras across much of the northern U.S. tonight into tomorrow while threatening satellite operations, GPS accuracy, and communications. Airlines, NASA, FAA and other operators have been alerted to prepare for potential impacts from the coronal mass ejection triggered by an X-class solar flare. Auroras may be visible as far south as Alabama and northern California under clear skies, though widespread public disruption isn’t expected. Scientists warn of possible further Earth-directed eruptions in the coming week, and astronauts on the ISS can shelter in shielded areas if radiation rises.
