Get ready for another spectacular showing of the Northern Lights across the United States! Thanks to increased geomagnetic activity, a rare opportunity has emerged for stargazers in up to 17 states to witness the aurora borealis. This resur...
The Northern Lights, or aurora borealis, are a result of charged particles from the sun interacting with Earth’s magnetic field. During geomagnetic storms, these particles accelerate down magnetic field lines at the poles, exciting atmospheric particles and creating the mesmerizing green and red ovals we see in the sky. The intensity and visibility of the aurora depend on the strength of the geomagnetic storm.
This week's G3 geomagnetic storm is caused by a co-rotating interaction region—a turbulent gap between fast and slow-moving solar wind streams—striking Earth's atmosphere. A similar event occurred on May 17 due to a coronal mass ejection, further contributing to the increased aurora sightings.
While the aurora season typically falls between September and March due to longer hours of darkness, the current solar maximum period allows for sightings even as we approach the summer solstice. The key is to find locations with minimal light pollution and clear skies, preferably facing north. Check NOAA's aurora viewline for the most accurate predictions.
**How to Prepare:**
**Who This Affects Most:**
The Northern Lights are caused by charged particles from the sun interacting with Earth's magnetic field.
The best time to view the Northern Lights is typically between 10 p.m. and 2 a.m., during periods of high geomagnetic activity.
Northern states like Washington, Idaho, Montana, North Dakota, and Minnesota offer prime viewing locations. In Wisconsin, Newport State Park, and the Kettle Moraine State Forest are recommended spots.
No, the Northern Lights are visible to the naked eye. However, a dark location away from city lights will enhance the viewing experience.
