A penumbral eclipse of the Moon occurred on 18 August, 0555 UT Old Style, with maximum eclipse at 08:40 UT. This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 3 hours and 5 minutes, just 52% of the Moon's disc was in partial shadow (with no part of it in complete shadow).

The penumbral eclipse lasted for 3 hours and 5 minutes. Maximum eclipse was at 08:40:14 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.
