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 (on December 12, 2020).

Visibility[edit]

Animated path

Chile[edit]

Totality made landfall in Puerto Saavedra, before traversing through portions of Araucanía Region, Los Ríos Region, and a very small part of Bío Bío Region.[1] Cities in the path included Temuco, Villarrica, and Pucón. Totality was also visible on Mocha Island. The eclipse's path was similar to the solar eclipse of February 26, 2017. It occurred just 17 months after the solar eclipse of July 2, 2019 and, like the 2019 eclipse, was also visible from Chile and Argentina. It was also a partial solar eclipse in Bolivia, Brazil, Ecuador, Paraguay, Peru and Uruguay.

Argentina[edit]

Totality was visible across the Northern Patagonia (specifically the provinces of Neuquén and Río Negro), passing through cities including Piedra del Águila, Sierra Colorada, Ministro Ramos Mexía, Junín de los Andes, and partially in San Martín de los Andes and San Carlos de Bariloche.

Scientific observations[edit]

The ionospheric effects of the eclipse were expected to be monitored as part of the December 2020 Eclipse Festival of Frequency Measurement, a citizen science experiment organized through the Amateur Radio Science Citizen Investigation (HamSCI).[2] Also, a prediction was made for a group of ionospheric stations in South America, using a numerical model (SUPIM-INPE), of the ionospheric response to this event.[3]

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.[4]

Note: Partial solar eclipses on February 15, 2018, and August 11, 2018, occurred during the previous semester series.

Saros 142[edit]

It is a part of Saros cycle 142, repeating every 18 years, 11 days, containing 72 events. The series started with partial solar eclipse on April 17, 1624. It contains one hybrid eclipse on July 14, 1768, and total eclipses from July 25, 1786 through October 29, 2543. The series ends at member 72 as a partial eclipse on June 5, 2904. The longest duration of totality will be 6 minutes, 34 seconds on May 28, 2291. All eclipses in this series occurs at the Moon’s descending node.[5]

Series members 17–41 occur between 1901 and 2359

Metonic cycle[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 descending node.

21 events between July 22, 1971 and July 22, 2047
