Solar eclipse of December 14, 2020

A total solar eclipse will occur 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. The Moon’s apparent diameter will be larger because the Moon occurs only 1.8 days after perigee (Perigee on December 12, 2020).

The path is similar to the solar eclipse of February 26, 2017. It takes place just 17 months after the solar eclipse of July 2, 2019 and, like the 2019 eclipse, is also visible from Chile and Argentina. It is also a partial solar eclipse in Bolivia, Brazil, Ecuador, Paraguay, Peru and Uruguay.

This solar eclipse will occur one lunar year after the annular solar eclipse on December 26, 2019.

Visibility

Chile

Totality will be visible in portions of Araucanía Region, Los Ríos Region, and a very small part of Bío Bío Region. Cities in the path include Temuco, Villarrica, and Pucón. Totality will also be visible on Mocha Island.

Argentina

Totality will also be visible across the Northern Patagonia Region (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.

Solar eclipses of 2018–2021

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.[1]

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

Saros 142

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.[2]

Metonic cycle

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.
