A total solar eclipse occurred at the Moon's ascending node of orbit on Tuesday, July 2, 2019,[1][2][3][4] with a magnitude of 1.0459. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's and the apparent path of the Sun and Moon intersect, blocking all direct sunlight and turning daylight into darkness; the Sun appears to be black with a halo around it. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. 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.
List of major cities in the path of totality[edit]

- Junín, Buenos Aires, Argentina[5]
Images[edit]
Visibility[edit]
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]
Oeno Island[edit]
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]
Chile[edit]
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]
Argentina[edit]
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.

Solar eclipses of 2018–2021[edit]
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]
The partial solar eclipses on February 15, 2018 and August 11, 2018 occur in the previous lunar year eclipse set.

Saros 127[edit]
This eclipse is a part of Saros series 127, repeating every 18 years, 11 days, and containing 82 events. The series started with a partial solar eclipse on October 10, 991 AD. It contains total eclipses from May 14, 1352 through August 15, 2091. There are no annular or hybrid eclipses in this set. The series ends at member 82 as a partial eclipse on March 21, 2452. 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 totality was produced by member 31 at 5 minutes, 40 seconds on August 30, 1532. All eclipses in this series occur at the Moon’s ascending node of orbit.[10]

Inex series[edit]
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 19th century:
- Solar Saros 120: Total Solar Eclipse of 1816 Nov 19
- Solar Saros 121: Hybrid Solar Eclipse of 1845 Oct 30
- Solar Saros 122: Annular Solar Eclipse of 1874 Oct 10

Metonic series[edit]
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.
