September 17 brings a supermoon and a partial eclipse this year. Mostly clear skies should give Indiana a good view of the earth's shadow on the moon.

A partial lunar eclipse happens when the Earth passes between the sun and moon, casting a shadow that darkens a sliver of the moon and appears to take a bite out of it. Since the moon will inch closer to Earth than usual, it’ll appear a bit larger in the sky. The supermoon is one of three remaining this year.
