Northern lights set the sky aglow amid powerful geomagnetic storm

Millions of Americans were able to see the magical glow of the northern lights on Friday night when a powerful geomagnetic storm reached Earth. 

The northern lights, also known as the aurora borealis, were predicted to be visible as far south as Alabama and Northern California. People reported seeing the lights as far south as Florida and Oklahoma. 

Some areas, like New York City, were impacted by cloud cover and missed out on the spectacular show, but the phenomenon is expected to last through the weekend and possibly into next week.
