The National Oceanic and Atmospheric Administration (NOAA) has issued a forecast for a G1-class geomagnetic storm, creating the potential for the northern lights to be visible across parts of the northern United States and Canada. According to the NOAA Space Weather Prediction Center, the activity is driven by a stream of fast-moving solar wind flowing from a large coronal hole on the sun. As these charged particles collide with Earth’s magnetic field and upper atmosphere, they excite oxygen and nitrogen molecules, producing the green, red, and purple displays known as the aurora borealis.
NOAA Forecasts G1 Geomagnetic Storm With Potential Northern Lights Visibility
Viewing Expectations and Geography
The geomagnetic activity is expected to push the aurora farther south than usual, with the most favorable viewing conditions occurring in northern regions. Based on NOAA’s projected viewline, the best odds for visibility include Alaska, Montana, North Dakota, Minnesota, and Maine. Northern portions of Washington, Idaho, Wisconsin, Michigan, New York, Vermont, and New Hampshire may also experience sightings.
The agency emphasizes that geography and local conditions remain critical factors. Residents are advised that the closer they are to the Canadian border, the better their chances of success. Widespread visibility across the central or southern U.S. is not expected under the current forecast. Experts suggest that a clear, unobstructed view of the northern horizon is essential, and observers should prioritize dark locations far from city light pollution.
Optimizing the Experience
For those attempting to witness the display, NOAA recommends that observers allow approximately 20 minutes for their eyes to adjust to the darkness. The highest probability of visibility is expected to run between 10 p.m. and 2 a.m. local time, when the sky is darkest and the aurora oval is most active. Because auroras can be faint and move quickly, patience is required; the display can brighten and fade rapidly throughout the night.
Potential observers are encouraged to check local cloud forecasts before traveling, as cloud cover can block the view. Because geomagnetic conditions can change within minutes, officials suggest monitoring the real-time aurora forecast available through the Forbes and Usnews, as well as mobile applications that provide live solar wind data.
Smartphone and Camera Tips
Modern technology can often capture the beauty of the northern lights more effectively than the human eye, as cameras are capable of recording colors that may appear faint to the unaided viewer. For those using smartphones, experts suggest using “Night Mode” or long-exposure settings while keeping the device steady on a tripod or stable surface.
For users with dedicated cameras, setting the aperture to f/4 or lower and focusing at infinity is recommended. Regardless of the equipment used, officials note that the primary factors for a successful sighting remain finding a dark, high vantage point and having a clear view of the northern horizon. While the current event is classified as a minor G1 storm, experts note that even with low geomagnetic activity, impressive displays can occur if the observer is in the right location under the aurora.
