A penumbral eclipse of the Moon occurs on Friday 21 October, 2450 UT, with maximum eclipse at 10:51 UT. In this extremely marginal eclipse, the Moon barely clips the edge of the Earth's penumbral shadow. This will cause a microscopic darkening of just 4% of the Moon's disc for 53 minutes and 30 seconds, which will be essentially impossible to see.

The penumbral eclipse lasts for 53 minutes and 30 seconds. Maximum eclipse is at 10:51:28 UT.

During this eclipse the Moon will be just a day before perigee, making it very large. At maximum eclipse it will be 0.560° in apparent diameter, which is 5.5% larger than 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 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.
