A fast solar wind stream from a large coronal hole could trigger geomagnetic activity tonight and into tomorrow, potentially producing northern lights as far south as New York, Idaho, and into northern Michigan and Maine.

Space weather watchers should monitor real-time updates on Space.com’s aurora blog and use location-based forecasts, with apps like My Aurora Forecast & Alerts and Space Weather Live for detailed conditions.

Aurora visibility depends on factors such as cloud cover, darkness, and Earth's magnetospheric response to the solar wind, so sightings aren’t guaranteed even during storms.

For best chances in the northern U.S., seek dark sky sites away from city lights and look north after nightfall; smartphone cameras can help capture faint auroras.

The strongest aurora activity is expected between late evening and early morning hours, with NOAA noting the possibility of minor to moderate geomagnetic storm conditions over the next several nights.

Elevated geomagnetic activity could persist into May 16 as the solar wind stream continues to interact with Earth's magnetic field.
