A partial solar eclipse will occur at the Moon's descending node of orbit on Sunday, August 2, 2065, with a magnitude of 0.4903. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

This will be the third of four partial solar eclipses in 2065, with the others occurring on February 5, July 3, and December 27.

Solar eclipses of 2062–2065

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.^[1]

The partial solar eclipses on July 3, 2065 and December 27, 2065 occur in the next lunar year eclipse set.

Saros 156

This eclipse is a part of Saros series 156, repeating every 18 years, 11 days, and containing 69 events. The series started with a partial solar eclipse on July 1, 2011. It contains annular eclipses from September 26, 2155 through April 7, 3075. There are no hybrid or total eclipses in this set. The series ends at member 69 as a partial eclipse on July 14, 3237. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of annularity will be produced by member 29 at 8 minutes, 28 seconds on May 3, 2516. All eclipses in this series occur at the Moon’s descending node of orbit.^[2]

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 descending node.
