A total eclipse of the Sun occurs on Tuesday 2 July, 2019 UT, lasting from 16:55–21:50 UT. A dramatic total eclipse will plunge the Sun into darkness for 4 minutes and 33 seconds at maximum, creating an amazing spectacle for observers in a broad path up to 201 km wide. It will be seen across the south Pacific and over Chile and Argentina. The partial eclipse will be visible in most of 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: 16:55:08 UT
Total eclipse begins: 18:01:04 UT
Maximum eclipse: 19:22:53 UT
Total eclipse ends: 20:44:44 UT
Partial eclipse ends: 21:50:34 UT

During this eclipse the Sun will be 0.524° in apparent diameter, 1.6% smaller than average. The Moon will be just 2 days before perigee, making it fairly large. At the start and end of the eclipse the Moon will be 0.541°, and at maximum eclipse 0.548°, which is 3.3% 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.

Pacific

The total eclipse narrowly misses the Pitcairn Islands at 18:28 UT. The path of the total eclipse is 169 km (105 miles) wide here, and the eclipse will last around 3 minutes 33 seconds; the islands will see a partial eclipse covering 97% of the Sun.

South America

The total eclipse reaches the mainland in its declining stages, but it will still be a spectular event even so. It makes landfall north of La Serena, Chile, at 20:39 UT. At this point, although the eclipse is in its closing stages, the duration of the total eclipse will still be an impressive 2 minutes 34 seconds on the centreline, and the path of the total eclipse will be 145 km (90.1 miles) wide. La Serena will see 2 minutes 15 seconds of totality, still a spectacular eclipse. The European Southern Observatory facility at La Silla is also in the path of totality; although well north of the centreline, it should see a total eclipse lasting 1 minute 51 seconds, from 20:39:24–20:41:15 UT.

The path of totality crosses into Argentina, moving rapidly now, and passes north of Río Cuarto just after 20:42 UT; the eclipse path at this point will be about 136 km (84.5 miles) wide, and the total eclipse will last for 2 minutes 14 seconds on the centreline, with Rio Cuarto seeing 1 minute 59 seconds.

The eclipse continues south-east, and finally ends just south of Buenos Aires at sunset, at 20:44 UT. At this point, totality will still last for over 2 minutes, as the sun sets totally eclipsed.

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.
