Timezone / Date

You have not selected a timezone for eclipse timings, so all times are shown in UT (essentially GMT).

Accuracy

Due to the erratic rotation of the Earth, the time and location of the eclipse cannot be forecast perfectly. This eclipse's time is estimated to be accurate ± 57m03s (with 95% confidence). This equates to an error in longitude of ± 14 degrees, or around ± 1481 km (920 miles) at the latitude of greatest eclipse.

A penumbral eclipse of the Moon occurred on 11 December, 1451 BC UT Old Style, with maximum eclipse at 15:49 UT. The Moon approached within 5% of the Earth's umbral shadow at maximum eclipse; 96% of the Moon's disc was partially shaded by the Earth, with the overall eclipse lasting 4 hours and 10 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 10 minutes. Maximum eclipse was at 15:49:45 UT.
