TL;DR Summary

The northern lights, or aurora borealis, may be visible in 17 U.S. states this week, but are unlikely to stretch into Iowa. The University of Alaska Fairbanks Geophysical Institute forecasts highly active auroral displays visible in parts of Canada and the U.S., including Minnesota and Wisconsin. To best see the lights, it is recommended to get away from city lights. The phenomenon is caused by solar winds colliding with Earth's magnetic field, producing a colorful glow in the upper atmosphere.
