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 ± 1h04m (with 95% confidence). This equates to an error in longitude of ± 15 degrees, or around ± 1618 km (1005 miles) at the latitude of greatest eclipse.

A total eclipse of the Moon occurred on 19 December, 1517 BC UT Old Style, with maximum eclipse at 23:36 UT. A shallow total eclipse saw the Moon in relative darkness for 51 minutes exactly. The Moon was 11% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours and 29 minutes in total.

The penumbral eclipse lasted for 5 hours and 47 minutes. The partial eclipse lasted for 3 hours and 29 minutes. The total eclipse lasted for 51 minutes exactly. Maximum eclipse was at 23:36:38 UT.
