ENGLISH, In. — A rare space phenomenon dazzled viewers across the U.S. this weekend. Aurora Borealis, also known as the "northern lights," filled the night sky with colors in the commonwealth.

The event was the result of a coronal mass ejection from the sun that hit the Earth as a magnetic storm.

Some members of the Louisville Astronomical tried to get a glimpse of the light show Saturday night.

According to the National Oceanic and Atmospheric Administration (NOAA), it was the most severe geometric storm since 2003.

“I mean, yesterday was an absolute … huge outburst," said Greg Miller, Louisville Astronomical Society member. 

Miller said he saw the northern lights for the first time a couple of decades ago and enjoyed seeing them again Friday night.

“It was really exciting the first time you got to see it," he said. "I can't believe I actually can see that from here because it's normally something that you only get to see from the Arctic Circle."

According to the NOAA, the sun goes through a cycle with minimums and maximums of sunspots, and more sunspots are possible closer to the maximum. If those sunspots are active, it could result in geometric storms that produce the northern lights.

“When they hit the earth, it's basically just a charged particle," Miller said. "They will start interacting with atoms in the atmosphere, like oxygen and nitrogen, depending (on) what it's interacting with and what the altitude is. That's what causes all the different colors." 

Many across the state photographed the results.

“Your eyes aren't really going to see the color as good as a camera is just because it's not as bright," Miller said. "The cameras will do a great job of pulling all that color out and everything. They just do a much better job, and it's really hard to not take a good picture of the auroras."

The National Weather Service said another severe to extreme geometric storm is possible, and it's likely another coronal mass ejection will hit the atmosphere late Sunday.
