A partial eclipse of the Moon occurred on 21 May, 1747 BC UT Old Style, with maximum eclipse at 09:07 UT. A tiny bite out of the Moon may have been visible at maximum, though just 5% of the Moon was shadowed in a partial eclipse which lasted for 52 minutes and 6 seconds. A shading across the moon from the Earth's penumbral shadow should have been visible at maximum eclipse.
The penumbral eclipse lasted for 4 hours and 21 minutes.
The partial eclipse lasted for 52 minutes and 6 seconds.
Maximum eclipse was at 09:07:55 UT.
