A penumbral eclipse of the Moon occurred on 31 July, 0245 BC UT Old Style, with maximum eclipse at 23:34 UT. At maximum eclipse, 88% of the Moon's disc was partially shaded by the Earth, which caused a slight shadow gradient across its disc; this subtle effect may have been visible to careful observers. No part of the Moon was in complete shadow. The eclipse lasted 4 hours and 2 minutes overall.

The penumbral eclipse lasted for 4 hours and 2 minutes. Maximum eclipse was at 23:34:22 UT.
