A penumbral eclipse of the Moon occurred on 22 March, 1671 BC UT Old Style, with maximum eclipse at 17:39 UT. In this extremely marginal eclipse, the Moon barely clipped the edge of the Earth's penumbral shadow. This caused a microscopic darkening of just 2% of the Moon's disc for 40 minutes and 30 seconds, which was essentially impossible to see.

The penumbral eclipse lasted for 40 minutes and 30 seconds. Maximum eclipse was at 17:39:17 UT.
