A penumbral eclipse of the Moon occurred on 22 April, 0640 BC UT Old Style, with maximum eclipse at 18:49 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 2% of the Moon's disc for 43 minutes and 48 seconds, which was essentially impossible to see.
The penumbral eclipse lasted for 43 minutes and 48 seconds.
Maximum eclipse was at 18:49:36 UT.
