A penumbral eclipse of the Moon occurred on 22 August, 1240 BC UT Old Style, with maximum eclipse at 04:28 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 17% of the Moon's disc for 2 hours and 1 minute, which was essentially impossible to see.

The penumbral eclipse lasted for 2 hours and 1 minute. Maximum eclipse was at 04:28:13 UT.
