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

NOAA warns that a series of coronal mass ejections (CMEs) that began on November 7 could spark geomagnetic storms from November 10–12, potentially making the Aurora Borealis visible across parts of 15 US states. Areas listed on the forecast include states such as New York, Minnesota, Iowa and Alaska, though actual visibility will depend on local conditions.

Auroras occur when charged particles from the Sun interact with Earth’s magnetic field and atmosphere. Forecasts give an indication of where displays are possible, but cloud cover, light pollution and the storm’s exact strength determine whether a dramatic show or a faint glow appears.

Tips for spotting the aurora

• Head to a dark, north‑facing location with a clear view of the horizon — rural areas and high ground are best.
• Check local weather and cloud cover before you go; clear skies greatly improve your chances.
• Use your phone camera to scan the sky — many smartphone cameras detect faint aurora colors before they’re obvious to the naked eye.
• Monitor the KP index and NOAA’s Space Weather Prediction Center (SWPC) for updates on geomagnetic activity and viewing latitudes.
• Dress warmly and be patient — auroras can appear suddenly and may last minutes to hours.

Where to follow official forecasts

For real‑time maps and alerts, check NOAA’s Space Weather Prediction Center (SWPC) and specialized aurora services or apps like “My Aurora Forecast” and SpaceWeatherLive. These tools show KP index predictions, cloud overlays and approximate viewing zones to help plan your outing.

Remember that aurora forecasting is not exact — strong events can be visible well south of the forecast line, while some areas inside the view zone may see little. The last widespread aurora event in the US was notable, but this week’s activity is expected to be less intense; it may still offer great viewing for many observers.
