Overview of the Geomagnetic Storm
A G2 geomagnetic storm is anticipated to illuminate the night sky across parts of the northern United States, beginning on the evening of March 18 and continuing into the early hours of March 19, 2026. The National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center has issued a storm watch due to a coronal mass ejection (CME) that occurred on March 16. This CME is expected to enhance auroral activity, potentially allowing the northern lights to be visible as far south as Illinois and Oregon.
States Likely to Experience Auroras
The NOAA has identified approximately 20 states where the northern lights may be visible, particularly in regions closer to the Canadian border. The states with the highest likelihood of seeing the auroras include:
- High Probability States: Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine.
- Additional States with Potential Visibility: Oregon, Nebraska, Iowa, Illinois, New York, Vermont, New Hampshire, and parts of Indiana, Ohio, and Pennsylvania.
The visibility of the auroras will depend on the intensity of the geomagnetic storm, local weather conditions, and light pollution.
Timing and Viewing Conditions
The best time to observe the northern lights is expected to be between 10 p.m. and 2 a.m. local time. Observers are advised to seek locations away from city lights and with a clear view of the northern horizon to enhance their chances of witnessing the phenomenon. The NOAA's aurora forecast indicates that the storm may peak around 2 a.m. ET on March 19.
Impact of the Geomagnetic Storm
While the primary allure of the geomagnetic storm is the potential for stunning auroral displays, such storms can also disrupt power systems and communication technologies. A G2 storm can lead to power fluctuations in weaker energy grids and may affect satellite operations. Additionally, migratory animals may experience navigation challenges during such storms.
Criticism and Concerns
Some experts caution that despite the promising forecasts, aurora visibility is never guaranteed. Factors such as magnetic field orientation, storm timing, and local weather conditions can significantly influence the likelihood of seeing the lights. NOAA has noted that while G2 conditions can push the auroral oval southward, the actual visibility may vary.

- “A coronal mass ejection (CME) is an eruption of solar material and magnetic fields. When they arrive at Earth, a geomagnetic storm can result,” — NOAA Space Weather Prediction Center
- “During the equinoxes, the orientation of the Earth’s poles is (almost) perpendicular to that of the Sun,” — Dr. Ciaran Beggan, British Geological Survey
Conclusion
The upcoming geomagnetic storm presents a rare opportunity for many in the northern U.S. to witness the northern lights. With proper planning and favorable conditions, observers may enjoy this natural spectacle, which is particularly enhanced during the spring equinox.
