Northern Lights Featured in
Wisconsin is well-positioned to enjoy the rare sight of aurora borealis. Beautiful dancing lights, coloring the skies in green, red, and purple, can be seen the best in the northeastern part of the state when the skies are dark, and there is enough geomagnetical activity that causes the natural phenomenon. Aurora chasers have to check special websites measuring geomagnetical or solar activity in KP-index. You need KP to be more than 5 to be able to see something in Wisconsin.
When you are expecting a solar storm that may cause auroras, try to get out of the city to minimize the impact of light pollution. You will most probably see a faint green glow on the horizon which will not be as impressive as auroras in Alaska or Yukon. However, if you photograph the phenomenon with a long exposure, you can actually see more glow and colors on camera than with a naked eye.
The season for aurora borealis in Northern Hemisphere generally runs from September through March. Autumn and spring are often experiencing solar storms so there are more chances to see aurora borealis. Summer skies are quite dark in Wisconsin, so seeing aurora is a possibility.
