A partial eclipse of the Moon occurred on 23 August, 1420 UT Old Style, with maximum eclipse at 15:16 UT. A tiny bite out of the Moon may have been visible at maximum, though just 4% of the Moon was shadowed in a partial eclipse which lasted for 45 minutes and 18 seconds. A shading across the moon from the Earth's penumbral shadow should have been visible at maximum eclipse.

The penumbral eclipse lasted for 4 hours and 18 minutes. The partial eclipse lasted for 45 minutes and 18 seconds. Maximum eclipse was at 15:16:17 UT.

Interactive Map

This map shows the visibility of the eclipse at maximum eclipse, when it was visible within the bright area on the map. Note that the map is approximate, and if you were near the edge of the area of visibility, the moon was very close to the horizon and may not have been practically visible.

You can use the zoom controls to zoom in and out, and pan to see areas of interest. The green marker in the centre shows where the Moon will be directly overhead at maximum eclipse.

The interactive map is currently not available.
