MADISON (WKOW) – If you look north tonight, you may be able to see the aurora borealis, also known as the aurora borealis.
Space Weather Forecast Center (SWPC) officials say a geomagnetic storm could make the lights visible for much of the northern United States, including here in Wisconsin.
According to the SWPC, the best viewing time will be from 7 pm Wednesday night to 3 am early Thursday. And even better, the sky will only be partially cloudy, which will better see them.

Aurora borealis occurs when electrically charged particles collide with neutral atoms in the upper atmosphere, creating a dazzling display of green light in the sky.
Be sure to get away from light pollution and get to rural areas with a very open horizon. Plan to allow your eyes to adjust to darkness for at least fifteen minutes before attempting to see the lights.
Tips for photographers: Use a tripod, set your exposure to long exposure, remove all filters, and set the focus to "infinity".
