Northern Lights Forecast: 18 U.S. States May See Auroras Sept 1‑2
A coronal mass ejection struck Earth on the afternoon of Sept. 1, 2025, and is set to generate a moderate‑to‑strong geomagnetic storm that could bring the northern lights as far south as the Midwest.
- The “cannibal” CME impacted around 5 p.m. EDT on Sept. 1, producing an expected G2‑G3 storm with a chance of reaching G4 levels.
- NOAA forecasts the Kp index to peak at 6.7 between 02:00 a.m. and 05:00 a.m. EDT on Sept. 2, extending the aurora view line across 18 states, including Alaska, Montana, Illinois, New York, Oregon and Washington.
- Visibility depends on clear, dark skies, minimal light pollution, and a north‑facing horizon; the best window is from midnight through the early pre‑dawn hours.
- To improve chances, travel to a dark location away from city lights, choose an unobstructed view of the northern horizon, stay patient for wave‑like activity, and monitor real‑time Kp forecasts via space‑weather apps.
- Why it matters: This rare event gives millions in mid‑latitude regions a chance to see auroras, while the storm could affect radio communications and, in extreme cases, power grids.
