Northern Lights Forecast: Where to See Aurora Displays This Weekend

The possibility of witnessing the aurora borealis, commonly known as the Northern Lights, has expanded for skywatchers across the United States. Forecasts indicate that a geomagnetic disturbance could make the lights visible in as many as ten states tonight, March 14, 2026, and potentially again this weekend. This follows recent displays that captivated observers as far south as Florida, and Texas.

Understanding the Geomagnetic Storm

The current heightened aurora activity is linked to increased solar activity. The Sun regularly emits streams of charged particles – primarily electrons and protons – known as the solar wind. When this wind interacts with Earth’s magnetosphere, the protective bubble around our planet, it can cause geomagnetic storms. These storms compress the magnetosphere and funnel charged particles down into the Earth’s atmosphere, primarily near the poles.

As these particles collide with atmospheric gases like oxygen and nitrogen, they excite the atoms to higher energy states. When these atoms return to their normal state, they release energy in the form of light, creating the vibrant colors of the aurora. Oxygen produces green and red light, although nitrogen emits blue and purple hues. The intensity and color of the aurora depend on the type of particle, its energy, and the altitude of the collision. Forbes details this process, explaining how stronger storms can push the aurora further from the poles.

Which States Might Spot the Lights?

While predicting the exact visibility of the aurora is challenging, current forecasts suggest the best viewing opportunities will be in the higher latitudes. States potentially in line for a show include Michigan, Minnesota, Wisconsin, Maine, New Hampshire, Vermont, New York, South Dakota, North Dakota, and Montana. Space.com reports that the aurora may be visible in nine states, while Yahoo News indicates a potential for visibility in ten. The Washington Post notes that while the peak of the recent activity may have passed, opportunities to view the lights still exist. The Washington Post suggests checking aurora forecasts for real-time updates.

Factors Influencing Visibility

Several factors beyond the geomagnetic storm’s intensity influence whether you’ll be able to see the aurora. Light pollution is a major obstacle. The darker your location, the better your chances. Getting away from city lights is crucial. Clear skies are also essential; cloud cover will obscure the view. Finally, a northern horizon is ideal, as the aurora typically appears as a diffuse glow or curtain of light along the northern edge of the sky.

How to Observe and Photograph the Aurora

No special equipment is needed to see the aurora, though binoculars or a camera can enhance the experience. For photography, a DSLR or mirrorless camera with a wide-angle lens and the ability to shoot in manual mode is recommended. A tripod is essential for long exposures. Settings will vary depending on the aurora’s brightness, but a good starting point is an ISO of 800-3200, an aperture of f/2.8 or wider, and an exposure time of 5-30 seconds. Experiment with different settings to find what works best for the conditions. The TODAY.com article provides additional tips for capturing the aurora with your camera.

The Science Behind the Forecasts

Forecasting aurora visibility relies on monitoring the Sun and the Earth’s magnetosphere. Space weather agencies, like the Space Weather Prediction Center (SWPC) operated by the National Oceanic and Atmospheric Administration (NOAA), employ data from satellites and ground-based observatories to track solar flares, coronal mass ejections (CMEs), and the resulting geomagnetic disturbances. CMEs are large expulsions of plasma and magnetic field from the Sun, and they are often the primary drivers of major geomagnetic storms. The SWPC issues alerts and forecasts to inform the public and critical infrastructure operators about potential space weather impacts.

Potential Impacts and Limitations

While the aurora is a beautiful phenomenon, strong geomagnetic storms can have practical consequences. They can disrupt radio communications, GPS signals, and power grids. Satellite operations can also be affected. However, the risk to most individuals is low. The current forecasts do not indicate a severe geomagnetic storm, so widespread disruptions are unlikely. It’s key to remember that space weather forecasting is still an evolving science, and predictions are not always accurate. The intensity and timing of geomagnetic storms can be difficult to predict with precision.

Looking ahead, continued monitoring of solar activity and improvements in space weather modeling will be crucial for providing more accurate and timely forecasts. As the Sun approaches the peak of its 11-year solar cycle, expected in 2025, we can anticipate more frequent and intense geomagnetic storms, and potentially more opportunities to witness the magic of the Northern Lights.
