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 ± 10m12s (with 95% confidence). This equates to an error in longitude of ± 2.55 degrees, or around ± 268 km (167 miles) at the latitude of greatest eclipse.

A total eclipse of the Moon occurred on 21 May, 0157 BC UT Old Style, with maximum eclipse at 13:59 UT. A dramatic total eclipse lasting 1 hour and 37 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 32 minutes in total.

The penumbral eclipse lasted for 5 hours and 19 minutes. The partial eclipse lasted for 3 hours and 32 minutes. The total eclipse lasted for 1 hour and 37 minutes. Maximum eclipse was at 13:59:53 UT.
