Northern lights wow viewers in the Lehigh Valley and across Pa. See their spectacular photos

BETHLEHEM, Pa. – People who stayed up late Sunday night were treated to an incredible display of the northern lights, which were visible in the Lehigh Valley.

Also known as the Aurora Borealis, the northern lights were visible thanks to a severe geomagnetic storm.

It was described by meteorologists as a “level 8 out of 9 episode” due to a coronal mass ejection, or massive storm on the sun.

• Lehigh Valley residents photographed the northern lights on Sunday
• The lights were visible thanks to severe geomagnetic storms
• According to posts on social media, the lights were visible all the way to North Carolina

On Sunday afternoon, NOAA's Space Weather Prediction Center said severe geomagnetic storms were underway, showing a level four out of five on the Geomagnetic Storm Impact scale.

According to posts on social media, the lights were visible all the way to North Carolina.

“Never would I (have) thought I'd get to photograph the northern lights in Pennsylvania,” wrote photographer Jim Trocchio, who shared a photo on Twitter.

“The northern lights are visible from the Lehigh Valley! What an awesome birthday present from mother nature!” wrote meteorologist Simon Wachholz.

Wachholz time-stamped his photo at 11:12 p.m. and said it was taken in Nazareth. He also shared a time lapse video.

Other shots were shared from across the state.

"Considering I took this in Pennsylvania, I'm proud. I couldn't ask for a better first experience viewing the Northern Lights,” wrote Bennett Geesaman, a former intern for John Fetterman (based on his Twitter profile).

“WOW! What an absolutely INCREDIBLE night here in central Pennsylvania. This was my view of the Northern Lights just before 3am at Shikellamy State Park (Overlook Section) in Union County, PA,” a tweet from a photographer named Tony Bendele said.

The northern lights could be visible again Monday night, forecasters say.
