The Northern Lights — formally known as Aurora Borealis — made an appearance in the skies over Montana early Friday morning.

Sean Batson shared this video with MTN News and wrote: "April 20th around 3am … north east of Great Falls"

Jim Thomas, who operates the Northern Lights "alert" site called Soft Serve News, notes: "Auroras are difficult to predict with precision. They have stops and starts (known as sub-storms). If you are out there, you need to be patient and lucky. Auroras happen in the upper atmosphere, so if there is cloud cover, you are out of luck."

Soft Serve News also offers a paid alert service (that includes a 14-day free trial) to notify subscribers of likely activity.

You can also visit the Space Weather Prediction Center website, which is operated by the National Oceanic & Atmospheric Administration.It provides information about the aurora borealis, and also features aurora forecasts.
