A penumbral eclipse of the Moon occurred on 30 April, 1718 BC UT Old Style, with maximum eclipse at 21:15 UT. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 88% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 4 hours and 29 minutes.

The penumbral eclipse lasted for 4 hours and 29 minutes. Maximum eclipse was at 21:15:10 UT.
