A penumbral eclipse of the Moon occurred on 11 December, 0485 BC UT Old Style, with maximum eclipse at 04:56 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 11% of the Moon's disc for 1 hour and 39 minutes, which was essentially impossible to see.

The penumbral eclipse lasted for 1 hour and 39 minutes. Maximum eclipse was at 04:56:28 UT.
