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 ± 37m11s (with 95% confidence). This equates to an error in longitude of ± 9 degrees, or around ± 978 km (608 miles) at the latitude of greatest eclipse.

A total eclipse of the Moon occurred on 13 August, 1231 BC UT Old Style, with maximum eclipse at 01:17 UT. A dramatic total eclipse lasting 1 hour and 43 minutes plunged the full Moon into deep darkness, as it passed right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may have been stained a deep orange or red colour at maximum eclipse. This was a great spectacle for everyone who saw it. The partial eclipse lasted for 3 hours and 49 minutes in total.

The penumbral eclipse lasted for 6 hours and 1 minute. The partial eclipse lasted for 3 hours and 49 minutes. The total eclipse lasted for 1 hour and 43 minutes. Maximum eclipse was at 01:17:14 UT.
