Aurora borealis, or sometimes called "Northern Lights," were seen by many people across southern Wisconsin and the Midwest during the twilight timeframe after sunset on Monday, October 24th.
Each occurence of aurora borealis is different in terms of colors, shapes, etc.
Below are a couple pictures taken by Brian Weinberg of the northern lights from State Highway 106, a couple miles west-northwest of Palmyra. They were forwarded to us by Mark Baden, Chief Meteorologist of WISN TV-12 Milwaukee; and Brian gave us permission to post them. Click on images for larger versions.
Here are a couple of photos from Scott Weberpal, taken about three miles north of Eagle at Scuppernong Prairie.
