A total solar eclipse will occur on September 14, 2099. 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.

Locations experiencing totality[]

It will begin at sunrise off the western coast of Canada, and move eastern across Canada (British Columbia, Alberta, and Saskatchewan) and the northern states of the United States (North Dakota, Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, West Virginia, Virginia and North Carolina). The eclipse will end in the Atlantic ocean, with partial visibility in parts of Europe, West Africa and throughout the entirety of North and South America.

The total eclipse will pass through the cities of Madison, Wisconsin, and Grand Rapids, Michigan. The last total solar eclipse over these two cities respectively was May 16, 1379,^[1]^[2] and April 18, 1558.^[3]

Although this solar eclipse does pass over a few large cities such as Minneapolis and Virginia Beach, it fails to offer totality in several major cities nearby, including most of Chicago and all of Washington D.C., Detroit, Cincinnati and Cleveland.^[4] Moreover, in Canada, the cities of Moose Jaw and Regina will be directly north of the path, but not in it.

Saros 136[]

Solar Saros 136, repeating every 18 years, 11 days, contains 71 events. The series started with partial solar eclipse on June 14, 1360, and reached a first annular eclipse on September 8, 1504. It was a hybrid event from November 22, 1612, through January 17, 1703, and total eclipses from January 27, 1721, through May 13, 2496. The series ends at member 71 as a partial eclipse on July 30, 2622, with the entire series lasting 1262 years. The longest eclipse occurred on June 20, 1955, with a maximum duration of totality at 7 minutes, 7.74 seconds. All eclipses in this series occurs at the Moon's descending node.^[6]

Inex series[]

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

Inex series members between 1901 and 2100:
January 14, 1926 (Saros 130)	December 25, 1954 (Saros 131)	December 4, 1983 (Saros 132)

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.
