A total solar eclipse will occur on Thursday, April 20, 2023. 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 the surface of the Earth, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.
Totality for this eclipse will be visible in the North West Cape peninsula and Barrow Island in Western Australia, eastern parts of East Timor, as well as Damar Island and parts of the province of Papua in Indonesia.[1]
It is a hybrid eclipse, with portions of its path near sunrise and sunset as annular.

Saros 129[]
It is a part of Saros cycle 129, repeating every 18 years, 11 days, containing 80 events. The series started with partial solar eclipse on October 3, 1103. It contains annular eclipses on May 6, 1464 through March 18, 1969, hybrid eclipses from March 29, 1987 through April 20, 2023 and total eclipses from April 30, 2041 through July 26, 2185. The series ends at member 80 as a partial eclipse on February 21, 2528. The longest duration of totality was 3 minutes, 43 seconds on June 25, 2131 . All eclipses in this series occurs at the Moon’s ascending node.[3]

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.

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.
