NOAA Forecasts Northern Lights Visibility Across 24 U.S. States Tonight
A minor geomagnetic storm may extend aurora visibility to 24 U.S. states tonight, according to NOAA forecasts.
The National Oceanic and Atmospheric Administration (NOAA) forecasts that a minor geomagnetic storm tonight could extend aurora visibility to 24 U.S. states. This event is linked to recent solar activity, including a strong solar flare detected on April 24, 2026. The storm is classified as G1 on NOAA's scale, with a Kp index expected to peak at 4.67, indicating potential for visible auroras.
States with higher probabilities of aurora visibility include Alaska, Washington, Idaho, Montana, North Dakota, and Minnesota. The southern visibility line extends to Wyoming, South Dakota, Nebraska, Iowa, Wisconsin, Michigan, Illinois, Indiana, Ohio, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire, and Maine.
Optimal viewing is anticipated between 10 p.m. and 2 a.m. local time. Clear skies, minimal artificial light, and an unobstructed northern horizon enhance visibility. Observers are advised to move away from urban centers and seek elevated or rural locations for the best experience.
