A penumbral eclipse of the Moon occurs on Friday 20 April, 2581 UT, with maximum eclipse at 06:30 UT. At maximum eclipse, 98% of the Moon's disc will be partially shaded by the Earth, which will cause a slight shadow gradient across its disc; this subtle effect may be visible to careful observers. No part of the Moon will be in complete shadow. The eclipse will last 4 hours and 32 minutes overall.

The penumbral eclipse lasts for 4 hours and 32 minutes. Maximum eclipse is at 06:30:34 UT.

Interactive Map

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