During this eclipse the Sun will be 0.532° in apparent diameter, around average. The Moon will be just a day past perigee, making it very large. At the start and end of the eclipse the Moon will be 0.553°, and at maximum eclipse 0.562°, which is 5.9% 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 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:||15:42:07 UT|
|Total eclipse begins:||16:38:44 UT|
|Maximum eclipse:||18:17:13 UT|
|Total eclipse ends:||19:55:29 UT|
|Partial eclipse ends:||20:52:14 UT|
The eclipse will be visible to millions in Mexico in Sinaloa, Durango, and Coahuila; in the USA from Texas through Ohio, New York, Vermont, and Maine; and in Quebec, New Brunswick, and Newfoundland in Canada.
The total eclipse begins at local dawn, 16:39 UT, just south of Starbuck Island in the South Pacific's Line Islands. The path is 144 km (89.5 miles) wide here, and the eclipse will last over 2 minutes.
After crossing the Pacific, the path of totality passes south of Mexico's Islas Revillagigedo; Isla Socorro will actually see a total eclipse, although it is somewhat north of the centreline. The eclipse then clips the Islas Marias, and hits the Mexican mainland just south of Mazatlán, at 18:09 UT. Here, the path of totality is 199 km (123.7 miles) wide, and the eclipse will last 4 minutes and 27 seconds.
The maximum eclipse occurs at 18:17 UT, near Nazas, Durango. The total eclipse will last 4 minutes 28.1 seconds, and will be visible over a path 198 km (123 miles) wide.
The path of totality then moves north-east through Durango to Coahuila; Torreón should see the total eclipse about 18:19 UT. The centre of the eclipse crosses the Mexico-US border at Piedras Negras / Eagle Pass, at 18:30 UT. The total eclipse at this point is still 4 minutes and 27 seconds on the centreline.
The total eclipse then heads north-east across the USA, crossing Texas, the south-east corner of Oklahoma, and Arkansas. The centreline of totality will pass just south of Dallas at 18:42 UT, with the total eclipse still over 4 minutes 20 seconds on the centreline. At 18:51 UT, the eclipse will be just south of Nimrod Lake, Arkansas — 21 years later, the total eclipse of August 12, 2045 crosses the same spot; part of the incredible USA eclipse bonanza.
The centre passes just north of Little Rock, Arkansas, before crossing into Missouri; St. Louis is unlucky again, being just north of the eclipse path for the second time in 7 years at 18:59 UT. The eclipse then passes into southern Illinois; it passes just south of Carbondale at 19:01 UT, at which point the total eclipse will last 4 minutes 9 seconds on the centreline, and be visible over a path 186 km (115.6 miles) wide. This same spot saw a total eclipse just 7 years previously, on August 21, 2017.
The eclipse path then crosses Indiana, with the centreline passing just south of Indianapolis at 19:08 UT; it then passes over Ohio, with the centreline passing over the waters of Lake Erie. The centreline will pass almost right over Buffalo, New York, at 19:20 UT; the eclipse duration is down to 3 minutes 45 seconds on the centreline, but that's still spectacular. With the path of totality still 179 km (111.2 miles) wide, Niagara Falls should see a good total eclipse.
Finally, the eclipse passes right over the island of Newfoundland, and then heads off into the Atlantic, to finish over the ocean at 19:55 UT.
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.

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.
