# Solar eclipse of September 12, 2034

An annular solar eclipse will occur at the Moon's ascending node of orbit on Tuesday, September 12, 2034, with a magnitude of 0.9736. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 5.7 days before apogee (on September 18, 2034, at 8:05 UTC), the Moon's apparent diameter will be smaller.
The eclipse will commence over the southern Pacific Ocean and then enter South America. Countries under the path include northern Chile, southern Bolivia, northern Argentina, southern Paraguay, and southern Brazil. The eclipse will then enter the Atlantic Ocean, and terminate approximately 2,000 miles (3,200 km) southeast of South America. A partial eclipse will be visible for parts of Central America, the Caribbean, South America, and Antarctica.

## Eclipse season

This eclipse is part of an eclipse 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 a fortnight.
Eclipse season of September 2034 :
| September 12 Ascending node (new moon) | September 28 Descending node (full moon) |
| Annular solar eclipse Solar Saros 135 | Partial lunar eclipse Lunar Saros 147 |

### Solar eclipses of 2033–2036

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.
The partial solar eclipse on July 23, 2036 occurs in the next lunar year eclipse set.
Solar eclipse series sets from 2033 to 2036 :

### Saros 135

This eclipse is a part of Saros series 135, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on July 5, 1331. It contains annular eclipses from October 21, 1511 through February 24, 2305; hybrid eclipses on March 8, 2323 and March 18, 2341; and total eclipses from March 29, 2359 through May 22, 2449. The series ends at member 71 as a partial eclipse on August 17, 2593. 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 was produced by member 16 at 10 minutes, 41 seconds on December 24, 1601, and the longest duration of totality will be produced by member 62 at 2 minutes, 27 seconds on May 12, 2431. All eclipses in this series occur at the Moon’s ascending node of orbit.

### 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.
Series members between 1801 and 2200 :
| June 26, 1805 (Saros 114) | May 27, 1816 (Saros 115) | April 26, 1827 (Saros 116) | March 25, 1838 (Saros 117) | February 23, 1849 (Saros 118) |

### 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.
Series members between 1801 and 2200 :
