A partial eclipse of the Moon occurred on 22 May, 1218 BC UT Old Style, with maximum eclipse at 17:23 UT. A tiny bite out of the Moon may have been visible at maximum, though just 10% of the Moon was shadowed in a partial eclipse which lasted for 1 hour and 8 minutes. 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 5 minutes. The partial eclipse lasted for 1 hour and 8 minutes. Maximum eclipse was at 17:23:22 UT.
