Amateur Skywatchers Discover New Form of Northern Lights - Video

The Northern Lights, which is scientifically called the Aurora Borealis, is a natural phenomenon, mainly seen in high-latitude regions.

A new form of the Northern Lights has been discovered by members of a research group that studies auroral emissions at the University of Helsinki.

According to the National Public Radio media outlet, physicist and professor Minna Palmroth, who leads the research group, recently co-authored a field guide to the Northern Lights, offering a detailed description of the aurora's types and forms.

After the release of the book, some amateur skywatchers made photos that showed a form of Northern Lights that did not fit into any of the provided categories. It had green, horizontal waves which ran in parallel. Some observers said it reminded them of sand formations and called them "the dunes."
