A penumbral eclipse of the Moon occurs on Friday 5 May, 2023 UT, lasting from 15:14–19:31 UT. The Moon will approach within 5% of the Earth's umbral shadow at maximum eclipse; 96% of the Moon's disc will be partially shaded by the Earth, with the overall eclipse lasting 4 hours and 18 minutes. While less dramatic than a partial eclipse (as no part of the Moon will be in complete shadow), a shading across the Moon should be readily visible to observers from most of Europe, Africa, Asia and Australia.

The timings of the eclipse are as follows. You will be able to see the eclipse if the Moon is up as seen from your location; but note that this penumbral eclipse will be very difficult to see in practice:

Penumbral eclipse begins: 15:14:10 UT
Maximum eclipse: 17:22:52 UT
Penumbral eclipse ends: 19:31:41 UT

During this eclipse the Moon will be 7 days after apogee and 5 days before perigee. At maximum eclipse it will be 0.532° in apparent diameter, which is around average. The statistics page has information on the ranges of the sizes of the Sun and Moon.

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.

Note that while all dates and times on this site (except where noted) are in UT, which is within a second of civil time, the dates and times shown in NASA's eclipse listings are in the TDT timescale.

The Sun and Moon distances are shown in km, and as a percentage of their minimum - maximum distances; hence 0% is the closest possible (Earth's perihelion, or the Moon's closest possible perigee) and 100% is the farthest (aphelion, the farthest apogee). The statistics page has information on the ranges of sizes of the Sun and Moon.
