A penumbral eclipse of the Moon occurred on 11 April, 1681 BC UT Old Style, with maximum eclipse at 03:32 UT. The Moon approached within 5% of the Earth's umbral shadow at maximum eclipse; 95% of the Moon's disc was partially shaded by the Earth, with the overall eclipse lasting 4 hours and 14 minutes. While less dramatic than a partial eclipse (as no part of the Moon was in complete shadow), a shading across the Moon should have been readily visible to observers.
The penumbral eclipse lasted for 4 hours and 14 minutes.
Maximum eclipse was at 03:32:21 UT.
