Surprise aurora light show: Look up, US

The aurora borealis may not be visible in North America, but on Monday evening it will look spectacular when seen from the southwest.

The aurora borealis is caused by the rapid acceleration of particles coming off the sun as it swings through a newly rotated orbit. When these particles collide with the Earth’s upper atmosphere, or magnetosphere, it sends a sudden burst of light and glowing particles floating through the sky.

While we will not see the Northern Lights in the United States due to our relatively low latitude, the Northwest, Alaska, and Western Canada will see stunning auroras and some may even break through for an impressive show in the sky.

Fog may cause delays in the Northwest on Monday evening. Weather conditions are expected to improve with a mostly clear sky near the coast.

The next chance to see a show this fall will be on Oct. 1.
