According to Science Buzz, astronomers are predicting some sexy Northern Lights tonight:
A major eruption on the Sun on June 7 sent high-energy particles spewing into space. They are expected to reach Earth on the night of Wednesday, June 8 (Minnesota time). Astronomers are predicting a major aurora event, with the Northern Lights visible overhead as far south as Milwaukee, and possibly visible on the northern horizon as far south a southern Indiana and Washington DC!
The most recent case of awesome Northern Lights in Duluth I remember was seven years ago. Tomasz Majewski captured the image above for Perfect Duluth Day from his home in the Piedmont neighborhood on Nov. 7, 2004.
