Geomagnetic Storm to Bring Rare Aurora Borealis Display Across Midwest and Northeast
18 Aug
Summary
- Geomagnetic storm expected to spark Northern Lights in 15 U.S. states
- Aurora borealis display predicted to peak between 11 PM and 5 AM on Aug 19
- Large coronal hole on the sun leading to high-speed solar wind toward Earth
According to forecasts, a geomagnetic storm is expected to bring a rare and vibrant aurora borealis display to the night skies across 15 U.S. states tonight and tomorrow morning. The storm, driven by a high-speed stream of solar wind, is predicted to peak between 11 PM and 5 AM on August 19, with the best chances of seeing the Northern Lights in Alaska, Montana, North Dakota, and other northern states.
A large coronal hole on the sun's surface has led to the ejection of this fast-moving solar wind, which is now interacting with Earth's magnetic field. This interaction is expected to increase geomagnetic activity, potentially reaching "active" and "minor storm" levels over the next couple of days. For skywatchers in the affected regions, the aurora may be visible low on the northern horizon, even if not directly overhead.
Experts advise finding a north-facing spot with clear views and minimal light pollution for the best chance of catching the colorful celestial display. Several mobile apps are also available to track real-time aurora forecasts and increase the odds of witnessing this rare natural phenomenon.
