A penumbral eclipse of the Moon occurs on Sunday 20 December, 2048 UT, with maximum eclipse at 06:26 UT. At maximum eclipse, 96% 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 42 minutes overall.

The penumbral eclipse lasts for 4 hours and 42 minutes. Maximum eclipse is at 06:26:16 UT.

During this eclipse the Moon will be just a day before apogee, making it very small. At maximum eclipse it will be 0.498° in apparent diameter, which is 6.3% smaller than average. The statistics page has information on the ranges of the sizes of the Sun and Moon, and the Moon data page displays detailed information on the Moon's key dates.

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.

The interactive map is currently not available.

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 listingsGSFC Eclipse Web Site

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, and the Moon data page displays detailed information on the Moon's key dates.
