Heads up aurora chasers! The northern lights may light up skies across the northern U.S. tonight (Jan. 2-3) according to the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center (SWPC).
An incoming coronal mass ejection (CME) — a vast plume of plasma and magnetic field from the sun — is forecast to deliver Earth a blow sometime on late Jan. 2 but more likely in the early hours of Jan. 3, according to the U.K. Met Office. If it arrives as expected, the CME could trigger minor (G1) to moderate (G2) geomagnetic storm conditions.
