A penumbral eclipse of the Moon occurred on 22 October, 0817 BC UT Old Style, with maximum eclipse at 22:22 UT. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 77% 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 39 minutes.

The penumbral eclipse lasted for 3 hours and 39 minutes. Maximum eclipse was at 22:22:25 UT.
