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 ± 20m03s (with 95% confidence). This equates to an error in longitude of ± 5 degrees, or around ± 536 km (333 miles) at the latitude of greatest eclipse.

A total eclipse of the Moon occurred on 17 August, 0952 BC UT Old Style, with maximum eclipse at 11:46 UT. The Moon was plunged into darkness for 1 hour and 5 minutes, in a deep total eclipse which saw the Moon 21% 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 21 minutes in total.

The penumbral eclipse lasted for 5 hours and 19 minutes. The partial eclipse lasted for 3 hours and 21 minutes. The total eclipse lasted for 1 hour and 5 minutes. Maximum eclipse was at 11:46:10 UT.
