A total solar eclipse occurred at the ascending node of the Moon's orbit on Tuesday, July 2, 2019,[1][2][3][4] with an eclipse magnitude of 1.0459. Totality was visible from the southern Pacific Ocean east of New Zealand to the Coquimbo Region in Chile and Central Argentina at sunset, with the maximum of 4 minutes 33 seconds visible from the Pacific Ocean. The Moon was only 2.4 days before perigee (Perigee on July 5, 2019), making it fairly large.

Another solar eclipse occurred one lunar year after this eclipse, on June 21, 2020. A total solar eclipse crossed this region of the Earth on December 14, 2020.
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.
Following the North American solar eclipse of August 21, 2017, Astronomers Without Borders collected eclipse glasses for redistribution to Latin America and Asia for the 2019 eclipses.[6]
Totality travelled over areas with low levels of humidity and light pollution, allowing for very good observations. Several major observatories experienced totality, including the European Southern Observatory.[7][8]
The first land surface and the only Pacific island from which totality was visible is Oeno Island, an uninhabited atoll in the Pitcairn Islands.[8]
Totality was visible in a large portion of Coquimbo Region and small parts of Atacama Region. Cities in the path included La Serena and La Higuera. Approximately 300,000 people visited La Serena to view the event.[7] Tickets to view the eclipse from the European Southern Observatory were sold for US$2000 each.[8]
Totality was visible in the provinces of San Juan, La Rioja, San Luis, Córdoba, Santa Fe, and Buenos Aires. Cities in the path included San Juan and Río Cuarto.[8] The path of totality finished at the Samborombon Bay, where the eclipsed sunset was observed from San Clemente del Tuyu.
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.[9]
Note: Partial solar eclipses on February 15, 2018, and August 11, 2018, occurred during the previous semester series.

It is a part of Saros cycle 127, repeating every 18 years, 11 days, containing 82 events. The series started with partial solar eclipse on October 10, 991 AD. It contains total eclipses from May 14, 1352 through August 15, 2091. There are no annular eclipses in this series. The series ends at member 82 as a partial eclipse on March 21, 2452. The longest duration of totality was 5 minutes, 40 seconds on August 30, 1532. All eclipses in this series occurs at the Moon’s ascending node.[10]

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.

In the 22nd century:
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.
