A penumbral eclipse of the Moon occurred on 20 January, 0086 BC UT Old Style, with maximum eclipse at 00:27 UT. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 67% 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 3 hours and 42 minutes.

The penumbral eclipse lasted for 3 hours and 42 minutes. Maximum eclipse was at 00:27:57 UT.
