Solar eclipse of April 8, 2024

A total solar eclipse will take place at the Moon’s ascending node of the orbit on Monday, April 8, 2024, visible across North America and dubbed the Great North American Eclipse (also Great American Total Solar Eclipse and Great American Eclipse) by some of the media.[1][2][3] A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring only 1 day after perigee (Perigee on April 7, 2024), the Moon's apparent diameter will be larger. With a magnitude of 1.0566, its longest duration of totality will be of four minutes and 28.13 seconds near the town of Nazas, Durango, Mexico, and the nearby city of Torreón, Coahuila.

This eclipse will be the first total solar eclipse to be visible from Canada since February 26, 1979,[4] the first in Mexico since July 11, 1991,[5] and the first in the U.S. since August 21, 2017. It will be the only total solar eclipse in the 21st century where totality is visible in Mexico, the United States of America, and Canada.[6]

The next solar eclipse occurs 177 days later.

Visibility
Animation of path

Totality will be visible in a narrow strip in North America, beginning at the Pacific coast, then ascending in a northeasterly direction through Mexico, the United States, and Canada, before ending in the Atlantic Ocean.

Mexico

In Mexico, totality will pass through the states of Sinaloa (including Mazatlán), Durango (including Durango and Gómez Palacio) and Coahuila (including Torreón, Matamoros, Monclova, Sabinas, Ciudad Acuña and Piedras Negras).

United States

In the United States, totality will be visible through the states of Texas (including parts of San Antonio, Austin, and Fort Worth and all of Arlington, Dallas, Killeen, Temple, Texarkana, Tyler and Waco), Oklahoma, Arkansas (including Hot Springs, Jonesboro, and Little Rock), Missouri, Illinois (including Carbondale), Kentucky, Indiana (including Bloomington, Evansville, Indianapolis, Muncie, Terre Haute, and Vincennes), Michigan (a very small area), Ohio (including Akron, Dayton, Lima, Roundhead, Toledo, Cleveland, Warren, Newton Falls and Austintown), Pennsylvania (including Erie), Upstate New York (including Buffalo, Rochester, Syracuse, the Adirondacks, Potsdam, and Plattsburgh), and northern Vermont (including Burlington), New Hampshire, and Maine,[7][8] with the line of totality going almost directly over the state's highest point Mount Katahdin. The largest city entirely in the path will be Dallas, Texas. It will be the second total eclipse visible from the central United States in just 7 years, after the eclipse of August 21, 2017.

Totality will pass through the town of Wapakoneta, Ohio, home of Neil Armstrong, the first person to set foot upon the Moon.

Canada

In Canada, the path of totality will pass over parts of Southern Ontario (including Leamington, Hamilton, Niagara Falls, Kingston, Prince Edward County, and Cornwall), parts of southern Quebec (including Montreal, Sherbrooke and the Mont Mégantic Observatory),[9] central New Brunswick (including Fredericton and Miramichi),[10] western Prince Edward Island (including Tignish and Summerside),[11], the northern tip of Cape Breton Island, Nova Scotia, [12] and central Newfoundland (including Gander and Grand Falls-Windsor). Then, it will vanish on the eastern Atlantic coast of Newfoundland. (Some of the Canadian cities listed, such as Hamilton and Montreal, are on an edge of the path of totality. Windsor, London, Toronto and Ottawa lie just north of the path of totality, and Moncton lies just south of it.)

Europe

The eclipse will be partially seen in Svalbard (Norway), in Iceland, Ireland, west parts of Great Britain, north-west parts of Spain and Portugal, the Azores and Canary Islands.[13]

The path of this eclipse will cross the path of the prior total solar eclipse of August 21, 2017, with the intersection of the two paths being in southern Illinois, in Makanda, just south of Carbondale.[14] The cities of Benton, Carbondale, Chester, Harrisburg, Marion, and Metropolis in Illinois; Cape Girardeau, Farmington, and Perryville in Missouri, as well as Paducah, Kentucky, will be within a roughly 9,000 square mile intersection of the paths of totality of both the 2017 and 2024 eclipses, therefore earning the distinction of being witness to two total solar eclipses within a span of seven years.

Solar eclipses 2022–2025

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[15]

Saros 139

It is a part of saros series 139, repeating every 18 years, 11 days, 8 hours, containing 71 events. The series started with partial solar eclipse on May 17, 1501. It contains hybrid eclipses on August 11, 1627 through December 9, 1825 and total eclipses from December 21, 1843 through March 26, 2601. The series ends at member 71 as a partial eclipse on July 3, 2763. Members in the same column are one exeligmos apart and thus occur in the same geographic area.

The solar eclipse of June 13, 2132 will be the longest total solar eclipse since July 11, 1991 at 6 minutes, 55.02 seconds.

The longest duration of totality will be produced by member 39 at 7 minutes, 29.22 seconds on July 16, 2186.[16] This is the longest solar eclipse computed between 4000BC and 6000AD.[17]

After 16 July 2186, totality duration will decrease. All eclipses in this series occurs at the Moon’s ascending node.

Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
