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 ± 50m49s (with 95% confidence). This equates to an error in longitude of ± 12 degrees, or around ± 1301 km (808 miles) at the latitude of greatest eclipse.

A penumbral eclipse of the Moon occurred on 12 December, 1386 BC UT Old Style, with maximum eclipse at 20:42 UT. In a rare total penumbral eclipse, the entire Moon was partially shaded by the Earth (though none of it was in complete shadow), and the shading across the Moon should have been quite visible at maximum eclipse. The penumbral phase lasted for 4 hours and 51 minutes in all, though for most of it, the eclipse was extremely difficult or impossible to see.

The penumbral eclipse lasted for 4 hours and 51 minutes. Maximum eclipse was at 20:42:20 UT.
