A penumbral eclipse of the Moon occurred on 31 October, 0427 BC UT Old Style, with maximum eclipse at 16:21 UT. In this extremely marginal eclipse, the Moon barely clipped the edge of the Earth's penumbral shadow. This caused a microscopic darkening of just 3% of the Moon's disc for 46 minutes and 12 seconds, which was essentially impossible to see.

The penumbral eclipse lasted for 46 minutes and 12 seconds. Maximum eclipse was at 16:21:49 UT.
