Photos show the lights illuminating the sky in vivid color across the U.S. this week. They'll be visible again in some states on Thursday.

The Aurora Borealis was spotted in a large swath of states, including Idaho, Iowa, Missouri, New Mexico, New York, Oklahoma, South Dakota, Tennessee, Texas and Washington state. Northern lights were visible as far south as parts of Florida and Alabama, a relatively rare occurrence that highlights the severity of this week's storms.

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

The Northern Lights are appearing more frequently across the South. Here's why you were able to see them in Nashville.

Earlier this week, a powerful solar storm helped to unleash the northern lights in skies as far south as Florida. Here's how rare that is.

According to the forecast, northern states bordering Canada - including Idaho, Montana, North Dakota and Washington state - have the best chances of catching a glimpse of the northern lights. However, it could be possible to glimpse the aurora from farther away.
