A powerful geomagnetic storm has set the stage for a rare northern lights display across much of the United States tonight, June, 2025. Following two major coronal mass ejections from the sun, space weather experts report ongoing G3 (strong) and even G4 (severe) geomagnetic storm conditions, making auroras possible far beyond their usual range.
The best chances to see the aurora borealis tonight are in northern states like Alaska, Michigan, and Washington, but if the storm intensifies, the lights could be visible as far south as Illinois, Oregon, and even Alabama and California The Kp index, a measure of geomagnetic activity, is predicted to peak at.67, which could allow auroras to dip into the Midwest and parts of the Northeast.
For optimal viewing, head outside between p.m. and a.m. local time, away from city lights and under clear skies. While the aurora may be faint to the naked eye in southern regions, phone cameras with night mode can help capture the spectacle.
This rare opportunity comes with a warning: strong geomagnetic storms can disrupt power systems, satellites, and radio communications, but pose no direct health risks to people.
With the storm expected to subside after tonight, skywatchers are urged to look up—this could be the last chance for months to witness the northern lights this far south.
