The Northern Lights may be visible in the mainland U.S. this week due to a strong geomagnetic storm, according to the National Oceanic and Atmospheric Administration.

The phenomenon, known scientifically as the aurora borealis, typically occurs closer to the North Pole, near Alaska and Canada.

But the storm could push the aurora lights farther south Thursday and Friday, and if weather conditions permit, could be seen in regions of Pennsylvania, Iowa and Oregon.
