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).
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.
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.
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]
This eclipse took place one lunar year after the Solar eclipse of December 26, 2019.
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.

A total solar eclipse took place on December 4, 2002 with a magnitude of 1.0244. 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. It was visible from a narrow corridor in southern Africa, the Indian Ocean and southern Australia. A partial eclipse was seen from the much broader path of the Moon's penumbra, including most of Africa and Australia. During the sunset after the eclipse many observers in Australia saw numerous and unusual forms of a green flash.
An annular solar eclipse occurred at the Moon's descending node of the orbit on October 3, 2005 with a magnitude of 0.958. 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 only 4.8 days after apogee, the Moon's apparent diameter was smaller. It was visible from a narrow corridor through the Iberian peninsula and Africa. A partial eclipse was seen from the much broader path of the Moon's penumbra, including all of Europe, Africa and southwestern Asia. The Sun was 96% covered in a moderate annular eclipse, lasting 4 minutes and 32 seconds and covering a broad path up to 162 km wide. The next solar eclipse in Africa occurred just 6 months later.
