Northern Lights Visible Across Northern U.S. Due to Geomagnetic Storm

A geomagnetic storm has expanded the visibility of the aurora borealis into parts of the northern United States, offering a rare celestial display. The National Oceanic and Atmospheric Administration (NOAA) issued a Geomagnetic Storm Watch, noting that a mild to moderate storm could push the aurora borealis further south than usual.

The best viewing opportunities are expected in states such as Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine. If the storm intensifies, the aurora could become visible in regions as far south as Oregon, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, New York, Vermont, and New Hampshire.

Auroras occur when charged particles from the sun interact with Earth's magnetic field and atmosphere, resulting in vibrant displays of light. The current event is driven by a high-speed stream of solar wind escaping from a coronal hole on the sun, creating geomagnetic storm conditions strong enough to expand the aurora's reach.

For optimal viewing, observers are advised to seek areas with dark, clear skies away from city lights. The prime time to witness the aurora is typically between 10 p.m. and 2 a.m. local time. Even with ideal conditions, auroras can be unpredictable, so patience is key.
