A penumbral eclipse of the Moon occurred on 12 May, 0669 BC UT Old Style, with maximum eclipse at 16:39 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 10% of the Moon's disc for 1 hour and 24 minutes, which was essentially impossible to see.
The penumbral eclipse lasted for 1 hour and 24 minutes.
Maximum eclipse was at 16:39:00 UT.
