A total solar eclipse occurred at the ascending node of the Moon's orbit on Tuesday, July 2, 2019, 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. [1]
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. [2] [3]
The first land surface and the only Pacific island from which totality was visible is Oeno Island, an uninhabited atoll in the Pitcairn Islands. [3]
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. [2] Tickets to view the eclipse from the European Southern Observatory were sold for US$2000 each. [3]
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. [3] 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. [4]
Note: Partial solar eclipses on February 15, 2018, and August 11, 2018, occurred during the previous semester 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.

A total solar eclipse took place on June 21, 2001, with a magnitude of 1.0495. It was the first solar eclipse of the 21st century. 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. Occurring 2.2 days before perigee, the Moon's apparent diameter was larger. Depending on the zone it, could be seen June 20–22

The central shadow passed just south of Hawaii in early morning and ended over Central America near sunset.
A total solar eclipse occurred at the Moon's ascending node on 3 November 2013. It was a hybrid eclipse of the Sun with a magnitude of 1.0159, with a small portion over the western Atlantic Ocean at sunrise as an annular eclipse, and the rest of the path as a narrow total solar eclipse.

Occurring only 10 hours and 2 minutes before perigee, the moon's apparent diameter was too larger.
An annular solar eclipse occurred on Sunday, June 21, 2020. An annular solar eclipse is a solar eclipse whose presentation looks like a ring, or annulus; it occurs when the Moon's apparent diameter is smaller than the sun's, blocking most, but not all, of the sun's light. In this instance, the moon's apparent diameter was 0.6% smaller than the sun's.
A total solar eclipse took place on Monday, December 14, 2020, when the Moon passed between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. Totality occurred in a narrow path across Earth's surface across parts of the South Pacific Ocean, southern South America, and the South Atlantic Ocean, when the Moon's apparent diameter was larger than the Sun's so all direct sunlight was blocked. The partial solar eclipse was visible over a surrounding region thousands of kilometres wide, including parts of the Pacific Ocean, South America, southwestern Africa, and the Atlantic Ocean. The Moon's apparent diameter was larger than average because the eclipse occurred only 1.8 days after perigee.

An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible in Mexico, the United States, Azores Islands, Morocco and Algeria. It was the first annular solar eclipse visible in the US in 33 years. The moon's apparent diameter was near the average diameter because occurs 6.7 days after apogee and 7.8 days before perigee.
