A total eclipse of the Moon occurs on Thursday 10 December, 2448 UT, with maximum eclipse at 16:32 UT. The Moon will be plunged into darkness for 1 hour and 23 minutes, in a deep total eclipse which will see the Moon 35% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may be stained a deep red colour. The partial eclipse will last for 3 hours and 34 minutes in total.

The penumbral eclipse lasts for 5 hours and 42 minutes. The partial eclipse lasts for 3 hours and 34 minutes. The total eclipse lasts for 1 hour and 23 minutes. Maximum eclipse is at 16:32:36 UT.

During this eclipse the Moon will be 5 days after perigee and 7 days before apogee. 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.
