A total eclipse of the Sun occurs on Wednesday 11 May, 2078 UT, lasting from 15:17–20:31 UT. A dramatic total eclipse will plunge the Sun into darkness for 5 minutes and 40 seconds at maximum, creating an amazing spectacle for observers in a broad path up to 232 km wide. It will be seen across Mexico and the south-eastern US. The partial eclipse will be visible over most of North America.

The timings of the phases of the overall eclipse worldwide are as follows. In any particular place it will be seen for a significantly shorter duration as the shadow moves across the Earth:

Partial eclipse begins: 15:17:36 UT
Total eclipse begins: 16:11:44 UT
Maximum eclipse: 17:54:30 UT
Total eclipse ends: 19:37:11 UT
Partial eclipse ends: 20:31:22 UT

During this eclipse the Sun will be 0.528° in apparent diameter, 1.0% smaller than average. The Moon will be at perigee, making it extremely large. At the start and end of the eclipse the Moon will be 0.555°, and at maximum eclipse 0.565°, which is 6.4% larger than average; hence it will cover the Sun, making this a total eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon.

A major total eclipse will begin in the Pacific, then cross Mexico before running up the US Gulf coast, crossing the south-eastern states before running off to finish in the Atlantic. This will be a great spectacle for millions of people in the eclipse path.

Interactive Map

This map shows the visibility of the eclipse. The shaded area will see the total solar eclipse; however, near the edges of this area, the eclipse will be very short. The bold line shows the centre of the path, where the eclipse will last longest, so this is where you want to be if possible.

Use the zoom controls to zoom in and out; hover your mouse over any point on the centreline to see the time and duration of the eclipse at that point. You can pan and zoom the map to see detail for any part of the eclipse path.

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.
