Auroras may be visible tonight (June 25) across 14 US states as a stream of solar wind from the sun is forecast to trigger moderate geomagnetic storms, potentially causing auroral activity. According to NOAA’s Space Weather Prediction Center, the Kp index will peak at 5.67, indicating stronger auroral activity.
These conditions could push the auroral oval far enough south to be visible on the northern horizon in states like New York and South Dakota, especially from dark-sky locations with minimal light pollution. Alaska has the highest chance of seeing the northern lights tonight due to its proximity to high latitudes.
The UK Met Office predicts a fast wind will arrive late June 25, increasing the chance of auroras at high latitudes. However, short nights and lingering twilight may hamper viewing in some areas. To witness the northern lights from your location, head to a north-facing vantage point as far away from light pollution as possible, with the best time being around 1 a.m. local time.
The following states are forecasted to have a chance of seeing the northern lights tonight: Alaska, Minnesota, North Dakota, Montana, Maine, Michigan, Wisconsin, Vermont, New Hampshire, Washington, Oregon, Idaho, New York, and South Dakota.
