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 ± 1h20m (with 95% confidence). This equates to an error in longitude of ± 20 degrees, or around ± 2092 km (1300 miles) at the latitude of greatest eclipse.

A total eclipse of the Moon occurred on 13 August, 1668 BC UT Old Style, with maximum eclipse at 16:09 UT. The Moon barely edged into total eclipse for just 18 minutes and 18 seconds. With the Moon just 2% of its diameter into the Earth's umbral shadow, the Moon may have been quite bright, but even so, this should have been worth seeing. The partial eclipse lasted for 3 hours and 8 minutes in total.

The penumbral eclipse lasted for 5 hours and 5 minutes. The partial eclipse lasted for 3 hours and 8 minutes. The total eclipse lasted for 18 minutes and 18 seconds. Maximum eclipse was at 16:09:22 UT.
