A total eclipse of the Sun occurs on Monday 14 December, 2020 UT, lasting from 13:33–18:53 UT. A dramatic total eclipse will plunge the Sun into darkness for 2 minutes and 10 seconds at maximum, creating an amazing spectacle for observers in a path up to 90 km wide. It will be seen from the Pacific to the Atlantic via Chile and Argentina. The partial eclipse will be visible over southern South 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: 13:33:48 UT
Total eclipse begins: 14:32:28 UT
Maximum eclipse: 16:13:23 UT
Total eclipse ends: 17:54:13 UT
Partial eclipse ends: 18:53:00 UT

During this eclipse the Sun will be 0.542° in apparent diameter, 1.6% larger than average. The Moon will be just 2 days past perigee, making it fairly large. At the start and end of the eclipse the Moon will be 0.546°, and at maximum eclipse 0.555°, which is 4.6% 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.

The Pacific

The eclipse begins east of the Marquesas islands, and passes well north of Easter Island and south of the Juan Fernandez islands before reaching South America.

Chile, Argentina

The total eclipse reaches Chile at 16:01 UT, the centreline of the total eclipse making landfall just south of Punto Saavedra. The path is 90 km (55.9 miles) wide here, and the eclipse will last 2 minutes and 8 seconds on the centreline. In fact, the eclipse duration is at least this long for the whole of its time on land.

The eclipse moves south-east over Gorbea and Villarrica, and reaches the Argentina border at 16:05 UT. It crosses the country and reaches maximum eclipse at 16:13 UT; at this point, the total eclipse will last 2 minutes 9 seconds on the centreline, and will be visible over a path 90 km (55.9 miles) wide.

The total eclipse passes Valcheta about 16:18 UT; 2 minutes later it reaches the Golfo San Matías, just south of San Antonio Oeste. The centreline of the eclipse touches land again around Moron, and finally heads into open ocean about 16:24 UT. It then heads off over the Atlantic towards Africa, but ends before it reaches land.

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.
