The partial eclipse will begin at 9:34 pm; totality will begin at 10:41 pm and end at 11:41 pm. Sunglasses are suggested for viewing the early stages.

A public presentation on coal-tar pavement sealants will be held Jan. 24 at 6 pm in the lecture hall of the Collins Learning Center. Tar-base pavement sealants are the primary source of toxic PAH pollution in urban landscapes. PAHs are harmful to human health and the aquatic life in our streams and lakes.
The Collins Learning Center, located at 2041 Michigan St. in Sturgeon Bay, is open 2-4 pm daily and during scheduled events.
