Detroit is not in the “path of totality” that will see the moon 100% obscure the sun, but we will be in a prime location to experience 80% obscurity.
As far as I can find there is only one event in Detroit to see the solar eclipse. The Michigan Science Center will be open from 12:00PM to 5:00PM. They note that the eclipse will happen between 1:03PM and 3:47PM with 2:27PM being the best time to see the most of the eclipse.
DO NOT LOOK DIRECTLY AT THE SUN!
NOT EVEN DURING THE ECLIPSE. DO NOT TRY TO VIEW THE ECLIPSE THROUGH A CAMERA OR CELLPHONE.
