High-speed winds from a spot on the sun’s surface may disrupt Earth’s magnetic field Tuesday, likely creating geomagnetic storm conditions that could make the northern lights appear in some northern U.S. states, according to the National Oceanic and Atmospheric Administration.

The northern lights may be visible in the United States on March 20, the same day as the spring equinox. Auroral activity is typically more abundant during the spring and autumn equinox due to the Russell-McPherron effect.
