Northern lights to illuminate skies across 21 US states amid solar storm

A powerful solar storm is set to light up the night skies across 21 U.S. states from Tuesday, 11 November, into early Wednesday, 12 November. The northern lights, caused by interactions between the Sun’s plasma and Earth’s magnetic field, will be visible from 6 p.m. to 6 a.m. Central Time. Observers are advised to seek dark, clear skies for optimal viewing.
