A penumbral eclipse of the Moon occurred on 23 April, 1020 BC UT Old Style, with maximum eclipse at 20:03 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 28 minutes.
The penumbral eclipse lasted for 4 hours and 28 minutes.
Maximum eclipse was at 20:03:42 UT.
