Northern Lights may be visible across 15 US states as geomagnetic storms arrive

NOAA forecasts that geomagnetic storms sparked by a trio of coronal mass ejections (CMEs) that began on November 7 could produce visible aurora displays from November 10 through November 12. The agency’s outlook shows about 15 US states fully or partially within the aurora view line — examples include New York, Minnesota, Iowa and Alaska — though visibility depends on local conditions.

Auroras are driven by charged particles from the Sun interacting with Earth’s magnetic field and upper atmosphere. Forecasts predict elevated geomagnetic activity this week, but the strength and extent of the lights can be unpredictable: cloud cover, local light pollution and the exact geomagnetic intensity will determine whether you see a vivid show or only faint glows.

Best tips for spotting the aurora

• Find a dark, north‑facing vantage point with a clear horizon and as little light pollution as possible — rural areas and high ground are best.
• Check the local weather and cloud cover before heading out; clear skies dramatically improve your chances.
• Use your phone camera to scan the sky: smartphone cameras often pick up faint aurora colors before they’re obvious to the naked eye.
• Watch the KP index and NOAA’s Space Weather Prediction Center forecasts for updates on geomagnetic activity.
• Be patient and dress warmly — aurora displays can appear suddenly and may persist for minutes to hours.

Where to follow official forecasts

For real‑time updates and maps, check NOAA’s Space Weather Prediction Center (SWPC) and dedicated aurora forecast services or apps like “My Aurora Forecast” or SpaceWeatherLive. These resources show KP index predictions, cloud cover overlays and approximate viewing latitudes.

Keep in mind that aurora forecasting is not an exact science. Even locations below the forecasted view line may catch a glimpse on a strong event, while some areas inside the view line may see little. The last major widespread aurora event in the US occurred last year — this week’s activity is expected to be noticeable for many, though likely not as intense as that storm.
