PITTSBURGH (KDKA) -- People in the Pittsburgh area could have a chance to see the Northern Lights tonight. 

NOAA's Space Weather Prediction Center has issued a geomagnetic storm watch for a G4 storm, that could trigger the Northern Lights around the Pittsburgh area this week. 

Pennsylvania and the Pittsburgh area fall between 7 and 9 on the K Index, which reflects the magnitude of a geomagnetic storm.

There are a few things you can do to try and see the Northern Lights.

Once it gets dark, find a spot away from lights, let your eyes adjust and look north.

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.
