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 ± 15m41s (with 95% confidence). This equates to an error in longitude of ± 3.92 degrees, or around ± 417 km (259 miles) at the latitude of greatest eclipse.

A total eclipse of the Moon occurred on 13 May, 0631 BC UT Old Style, with maximum eclipse at 05:01 UT. The Moon was plunged into darkness for 1 hour and 35 minutes, in a deep total eclipse which saw the Moon 47% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours and 47 minutes in total.

The penumbral eclipse lasted for 6 hours and 2 minutes. The partial eclipse lasted for 3 hours and 47 minutes. The total eclipse lasted for 1 hour and 35 minutes. Maximum eclipse was at 05:01:44 UT.
