A penumbral eclipse of the Moon occurred on 28 October, 0557 BC UT Old Style, with maximum eclipse at 19:37 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 15% of the Moon's disc for 1 hour and 54 minutes, which was essentially impossible to see.

The penumbral eclipse lasted for 1 hour and 54 minutes. Maximum eclipse was at 19:37:35 UT.
