A penumbral eclipse of the Moon occurred on 31 August, 1808 BC UT Old Style, with maximum eclipse at 12:21 UT. This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 3 hours and 3 minutes, just 51% of the Moon's disc was in partial shadow (with no part of it in complete shadow).

The penumbral eclipse lasted for 3 hours and 3 minutes. Maximum eclipse was at 12:21:28 UT.
