Northern Lights May Illuminate Skies Across Northern U.S. States on Christmas Eve

A minor (G1) geomagnetic storm is forecasted to enhance the visibility of the aurora borealis across several northern U.S. states on December 24-25, 2025. According to the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center, residents in Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine may have the opportunity to witness this natural light display.

The anticipated geomagnetic activity is attributed to a combination of high-speed solar wind from a coronal hole and a coronal mass ejection (CME) that occurred on December 20. While the CME is not expected to make a direct impact, it could pass close to Earth, potentially enhancing auroral activity.

For optimal viewing, NOAA recommends seeking dark, rural locations away from city lights and observing the northern sky between 10 p.m. and 2 a.m. local time. Clear skies are essential, as cloud cover can obstruct the view. Additionally, using space weather mobile applications can provide real-time updates on auroral activity.

The sun is currently near the peak of its 11-year solar cycle, known as the solar maximum, leading to increased solar activity and more frequent auroral displays. However, aurora visibility is influenced by various factors, including geomagnetic activity levels and local weather conditions.
