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.

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.

To photograph the northern lights, travel away from city lights to a dark or rural area and gain a good view of the northern horizon.

If you are using a professional camera, Adobe recommends first switching to manual mode. Then set your focus to infinity to focus on the farthest possible point.

Next, set your aperture to the lowest possible setting as this helps your camera focus on the sky and northern lights, not the surrounding environment.

You will also want to use a low shutter speed (~20 seconds) to allow your camera to capture a slow-moving aurora. If it is faster, then your shutter speed can be raised. Raise the ISO on your camera to at least 800 if the aurora is fairly bright, otherwise, if it is dim, raise your ISO to 2000. Adobe also recommends testing the shot with automatic white balance.

If you don't have all the fancy camera equipment, you can also attempt to photograph the northern lights with your smartphone camera in night mode.

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.
