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 ± 1h26m (with 95% confidence). This equates to an error in longitude of ± 21 degrees, or around ± 2301 km (1430 miles) at the latitude of greatest eclipse.

A total eclipse of the Moon occurred on 22 May, 1720 BC UT Old Style, with maximum eclipse at 14:49 UT. The Moon barely edged into total eclipse for 22 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 21 minutes in total.

The penumbral eclipse lasted for 5 hours and 32 minutes. The partial eclipse lasted for 3 hours and 21 minutes. The total eclipse lasted for 22 minutes and 18 seconds. Maximum eclipse was at 14:49:46 UT.
