A penumbral eclipse of the Moon occurred on 3 April, 0991 BC UT Old Style, with maximum eclipse at 07:23 UT. The Moon approached within 4% 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 13 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 13 minutes.
Maximum eclipse was at 07:23:23 UT.
