A partial eclipse of the Moon occurred on 31 August, 0321 BC UT Old Style, with maximum eclipse at 09:48 UT. A tiny bite out of the Moon may have been visible at maximum, though just 1% of the Moon was shadowed in a partial eclipse which lasted for 26 minutes and 36 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 9 minutes.
The partial eclipse lasted for 26 minutes and 36 seconds.
Maximum eclipse was at 09:48:15 UT.
