Lake Superior's north shore gives the Upper Midwest an open, dark northern horizon.
At 46.8° geographic latitude, aurora typically becomes visible here once the planetary Kp index reaches about 8. Stronger geomagnetic storms push the oval overhead and light up more of the sky.
The northern aurora season runs from late August to mid-April, when nights are long enough to be truly dark. Around midwinter the sky can stay dark almost all day; in high summer the midnight sun makes viewing impossible.
