A penumbral eclipse of the Moon occurred on 23 December, 0261 BC UT Old Style, with maximum eclipse at 20:23 UT. At maximum eclipse, 95% 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 32 minutes overall.

The penumbral eclipse lasted for 4 hours and 32 minutes. Maximum eclipse was at 20:23:09 UT.
