A partialsolar eclipse will occur at the Moon'sdescending node of orbit on Wednesday, July 11, 2029,[1] with amagnitude of 0.2303. Asolar eclipse occurs when theMoon passes betweenEarth and theSun, 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'sshadow misses the Earth.
This will be the third of four partial solar eclipses in 2029, with the others occurring onJanuary 14,June 12, andDecember 5.
A partial eclipse will be visible for parts of southernChile andArgentina.

This eclipse is part of aneclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by afortnight. The first and last eclipse in this sequence is separated by onesynodic month.

This eclipse is a member of asemester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternatingnodes of the Moon's orbit.[3]
The partial solar eclipses onJune 12, 2029 andDecember 5, 2029 occur in the next lunar year eclipse set.

This eclipse is a part ofSaros series 156, repeating every 18 years, 11 days, and containing 69 events. The series started with a partial solar eclipse onJuly 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 oneexeligmos 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’sdescending node of orbit.[4]

Themetonic 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.

This eclipse is a part of atritos cycle, repeating at alternating nodes every 135synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.
The partial solar eclipse on November 4, 2116 (part of Saros 164) is also a part of this series but is not included in the table below.

This eclipse is a part of the long periodinex cycle, repeating at alternating nodes, every 358synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.
