A total solar eclipse is forecast to occur on Saturday, September 4, 2100. 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.

It is a part of Saros cycle 146, repeating every 18 years, 11 days, containing 76 events. The series started with partial solar eclipse on September 19, 1541. It contains total eclipses from May 29, 1938 through October 7, 2154, hybrid eclipses from October 17, 2172 through November 20, 2226, and annular eclipses from December 1, 2244 through August 10, 2659. The series ends at member 76 as a partial eclipse on December 29, 2893. The longest duration of totality was 5 minutes, 21 seconds on June 30, 1992.

Inex series[edit]

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 3, 1927 (Saros 140)	December 14, 1955 (Saros 141)	November 22, 1984 (Saros 142)
November 3, 2013 (Saros 143)	October 14, 2042 (Saros 144)	September 23, 2071 (Saros 145)

Tritos series[edit]

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.
