Northern Lights Alert: Increased Geomagnetic Activity to Continue
Over two days the sun launched a barrage of coronal mass ejections (CMEs) — expulsions of plasma and magnetic field — toward Earth. The first two CMEs combined and formed a "cannibal CME" which hit on July 29 at 8:27 p.m. EDT (0027 on July 30), sparking a minor G1-class geomagnetic storm and triggering northern lights across the U.S. and Canada.
