A total eclipse of the Moon occurred on 20 July, 0811 BC UT Old Style, with maximum eclipse at 08:42 UT. The Moon was plunged into darkness for 1 hour and 19 minutes, in a deep total eclipse which saw the Moon 34% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours and 26 minutes in total.

The penumbral eclipse lasted for 5 hours and 20 minutes. The partial eclipse lasted for 3 hours and 26 minutes. The total eclipse lasted for 1 hour and 19 minutes. Maximum eclipse was at 08:42:33 UT.
