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:||15:46:51 UT|
|Total eclipse begins:||16:48:36 UT|
|Maximum eclipse:||18:25:32 UT|
|Total eclipse ends:||20:02:34 UT|
|Partial eclipse ends:||21:04:24 UT|
During this eclipse the Sun will be 0.527° in apparent diameter, 1.1% smaller than average. The Moon will be just 3 days past perigee, making it relatively large. At the start and end of the eclipse the Moon will be 0.535°, and at maximum eclipse 0.543°, which is 2.3% 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.
This will be visible as a spectacular total eclipse to millions of people in Oregon, Idaho, Wyoming, Nebraska, the north-east corner of Kansas, Missouri, southern Illinois, Kentucky, Tennessee, north-east Georgia, and the Carolinas.
The path starts in the Pacific well north of Hawaii at 16:48 UT, and then crosses to make landfall in the northern half of Oregon at 17:17 UT. The line of maximum eclipse hits the coast just south of Lincoln City; the path is 99 km (61.5 miles) wide here, so residents of Portland would be well advised to make the short trip south to the centreline, where the eclipse will last 1 minute 59 seconds (although getting inland away from the clouds may also be a good idea).
The eclipse then passes into Idaho and Wyoming, and enters Nebraska about 17:48 UT. The path width is up to 110 km (68.4 miles) here, and the duration on the centreline is 2 minutes 29 seconds.
The path of totality then clips the north-east corner of Kansas about 18:06 UT; it passes just north of Kansas City and crosses Missouri, where St. Louis is unluckily just north of the path. The centreline passes De Soto, just south of the city, at 18:18 UT, so the residents would be well advised to make a trip south for the day to see 2 minutes and 40 seconds of total eclipse.
The path then crosses the southern end of Illinois, passing just south of Carbondale at about 18:21 UT. Seven years later, the total eclipse of April 8, 2024 crosses the same spot; part of the incredible USA eclipse bonanza.
The eclipse is very close to maximum here, and in fact reaches maximum at 18:25 UT, in western Kentucky near Princeton. At this point the total eclipse will cover a path 115 km (71.5 miles) wide, and will last 2 minutes and 40 seconds on the centreline.
After maximum, the path of totality moves on southeast across Tennessee, and then clips North Carolina and Georgia before moving into South Carolina. Observers in Georgia will have to get into the very north-east corner of the state to be close to the centre of the eclipse, which will be there at 18:37 UT, with totality lasting 2 minutes 38 seconds.
The path of totality crosses South Carolina and reaches the ocean just north of Charleston, at 18:48 UT. The duration of the total eclipse will still be 2 minutes 33 seconds on the centreline, so it is still a spectacular eclipse — if the sky is clear; the path of totality is 115 km (71.5 miles) wide.
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.
This map sourced from NASA's Eclipse Web Site shows the visibility of the total solar eclipse. It also shows the broader area in which a partial eclipse will be seen. (Click on it for the full-sized version.)

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.
