A penumbral eclipse of the Moon occurred on 17 October, 1020 BC UT Old Style, with maximum eclipse at 17:59 UT. At maximum eclipse, 87% 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 3 hours and 50 minutes overall.
The penumbral eclipse lasted for 3 hours and 50 minutes.
Maximum eclipse was at 17:59:05 UT.
