Photos show Northern Lights seen from the Pittsburgh area
PITTSBURGH, Pa. (KDKA) -- The Northern Lights have been spotted in the Pittsburgh area once again!
The colorful auroras were seen late Monday night, just after 10 p.m. in Butler by Julie Krenitsky.
Marie Brosi shared a photo with KDKA First Alert Meteorologist Ray Petelin that was captured near Raccoon Creek State Park.
Jan Copeland McElhinny captured some bright green auroras in Evans City and shared the photo with KDKA First Alert Meteorologist Ray Petelin.
The Northern Lights were also seen by Ed Thompson in Whitehall around 2 a.m.
Bright pink and green auroras were captured in Indiana County, as well.
The northern lights have already graced the Pittsburgh area a couple of times this year.
Both the aurora borealis and the Perseid meteor shower were visible one night in August, making for a dazzling celestial show. Green, purple, red and pink hues were also visible in Western Pennsylvania skies back in May.
What causes the northern lights?
When a geomagnetic storm occurs, solar wind is sent toward Earth. Charged protons and electrons follow Earth's magnetic field and enter the Earth where the magnetic fields are the weakest: the poles. The electrons smash into all the different molecules that make up our atmosphere, creating a dazzling display of colors in the sky.
It's rare for the northern lights to be seen so clearly this far south. Most of the time, we're lucky if it even happens once a year.
