A partial eclipse of the Moon occurs on Sunday 21 July, 2176 UT, with maximum eclipse at 22:30 UT. A tiny bite out of the Moon may be visible at maximum, though just 6% of the Moon will be shadowed in a partial eclipse lasting for 56 minutes and 18 seconds. A shading across the moon from the Earth's penumbral shadow should be visible at maximum eclipse.

The penumbral eclipse lasts for 4 hours and 45 minutes. The partial eclipse lasts for 56 minutes and 18 seconds. Maximum eclipse is at 22:30:26 UT.

During this eclipse the Moon will be 5 days after apogee and 11 days before perigee. At maximum eclipse it will be 0.511° in apparent diameter, which is 3.8% 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.

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.
