A total solar eclipse will occur at the Moon's ascending node of orbit on Wednesday, April 20, 2061,[1] with a magnitude of 1.0475. 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 about 1.1 days before perigee (on April 21, 2061, at 4:00 UTC), the Moon's apparent diameter will be larger.[2]

Visibility

[edit]

The eclipse will begin over Southern Russia and eastern Ukraine at sunrise and the moon shadow will move rapidly in a northeastern direction over west Kazakhstan (West Kazakhstan Region). The shadow will cover the Urals and races over the Arctic Ocean in a north-westerly direction and reaches the Svalbard archipelago. At sunset the eclipse will end just before the coast of Greenland.

The greatest eclipse will be in Russia on the east of Komi Republic (in Europe), ~120 km to south-east of Pechora.

A partial solar eclipse will also be visible for parts of Eastern Europe, Asia, Alaska, and northwestern Canada.

Eclipse season

[edit]

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

Solar eclipses of 2058–2061

[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]

The partial solar eclipse on June 21, 2058 occurs in the previous lunar year eclipse set.

Saros 149

[edit]

This eclipse is a part of Saros series 149, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on August 21, 1664. It contains total eclipses from April 9, 2043 through October 2, 2331; hybrid eclipses from October 13, 2349 through November 3, 2385; and annular eclipses from November 15, 2403 through July 13, 2800. The series ends at member 71 as a partial eclipse on September 28, 2926. 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 will be produced by member 31 at 4 minutes, 10 seconds on July 17, 2205, and the longest duration of annularity will be produced by member 62 at 5 minutes, 6 seconds on June 21, 2764. All eclipses in this series occur at the Moon’s ascending node of orbit.[5]

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.

Tritos series

[edit]

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

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.
