A partial eclipse of the Moon occurred on 21 April, 1671 BC UT Old Style, with maximum eclipse at 01:01 UT. A tiny bite out of the Moon may have been visible at maximum, though just 7% of the Moon was shadowed in a partial eclipse which lasted for 57 minutes and 42 seconds. A shading across the moon from the Earth's penumbral shadow should have been visible at maximum eclipse.

The penumbral eclipse lasted for 4 hours and 10 minutes. The partial eclipse lasted for 57 minutes and 42 seconds. Maximum eclipse was at 01:01:43 UT.
