The northern lights could be visible across 10 U.S. states (or maybe more) tonight (Nov. 13-14) as soon as it gets dark, so it's worth keeping an eye on the sky throughout the evening, especially in areas with clear, dark skies.

Vivid auroras lit up skies across North America and Europe as a severe G4 geomagnetic storm, one of the strongest this solar cycle, rattled Earth's magnetic field.

Keep your eye on the sky Wednesday night, although it's not a lock that New Jerseyans will get another view of the colorful Northern Lights.

Geomagnetic storm activity is expected to continue this week, but will Nashville catch a second glimpse of the northern lights? Here's what to know.

To catch a glimpse, find a dark area away from city lights, such as a park or rural location, and check your local weather — clouds can easily block the show. The lights are typically best “within an hour or two” of midnight, meaning you should keep an eye out between 10 p.m. and 2 a.m., according to the SWPC.

The northern lights were visible Tuesday night across the Chicago area, illuminating the sky with brightly colorful displays due to severe solar storms.

Triggered by an intense geomagnetic storm, the northern nights made a rare visit to the Southland on Tuesday night, painting the skies above the Angeles National Forest in dazzling pink and purple hues.

Parts of Florida were treated to the aurora borealis this week. The show appears to be over, though — for now.

If you missed the northern lights the last two nights, you'll have another opportunity on Nov. 13, if the weather cooperates. Here is what to know.

Coronal mass ejections, or CMEs, are large clouds of ionized gas called plasma and magnetic fields that erupt from the sun’s outer atmosphere. When these outbursts are directed at Earth, they can cause major disturbances of Earth’s magnetic field, resulting in geomagnetic storms.
