A total eclipse of the Moon occurs on Friday 27 July, 2018 UT, lasting from 17:14–23:28 UT. A dramatic total eclipse lasting 1 hour and 43 minutes will plunge the full Moon into deep darkness, as it passes right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red colour at maximum eclipse. This will be a great spectacle for everyone who sees it from Europe, Africa, Asia, and Australia. The partial eclipse will last for 3 hours and 55 minutes in total.

The timings of the phases of the eclipse are as follows. You will be able to see each phase of the eclipse if the Moon is up at the corresponding time as seen from your location; however the penumbral phase will be very difficult to see in practice, so you may want to start watching at the partial phase:

Penumbral eclipse begins: 17:14:49 UT
Partial eclipse begins: 18:24:27 UT
Total eclipse begins: 19:30:15 UT
Maximum eclipse: 20:21:43 UT
Total eclipse ends: 21:13:12 UT
Partial eclipse ends: 22:19:00 UT
Penumbral eclipse ends: 23:28:37 UT

During this eclipse the Moon will be at apogee, making it very small. At maximum eclipse it will be 0.498° in apparent diameter, which is 6.2% smaller 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 various stages. The bright area in the middle will see the whole eclipse; the coloured bands to the right will see the start of the eclipse, and those on the left will see the end. 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. Hover your mouse over the tags to see what will be visible from each area on the map. 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.
