A totalsolar eclipse will occur at the Moon'sascending node of orbit on Wednesday, April 20, 2061,[1] with amagnitude of 1.0475. Asolar eclipse occurs when theMoon passes betweenEarth and theSun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon'sapparent 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 beforeperigee (on April 21, 2061, at 4:00 UTC), the Moon's apparent diameter will be larger.[2]
The eclipse will begin overSouthern Russia and easternUkraine at sunrise and the moon shadow will move rapidly in a northeastern direction over westKazakhstan (West Kazakhstan Region). The shadow will coverthe Urals and races over theArctic Ocean in a north-westerly direction and reaches theSvalbard archipelago. At sunset the eclipse will end just before the coast ofGreenland.
The greatest eclipse will be inRussia on the east ofKomi Republic (inEurope), ~120 km to south-east ofPechora.
A partial solar eclipse will also be visible for parts ofEastern Europe,Asia,Alaska, and northwesternCanada.

This eclipse is part of aneclipse 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 afortnight.

This eclipse is a member of asemester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternatingnodes of the Moon's orbit.[4]
The partial solar eclipse onJune 21, 2058 occurs in the previous lunar year eclipse set.

This eclipse is a part ofSaros series 149, repeating every 18 years, 11 days, 8 hours[5] and containing 71 events. The series started with a partial solar eclipse on August 21, 1664. It contains total eclipses fromApril 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 oneexeligmos 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’sascending node of orbit.[6]

This eclipse is a part of atritos cycle, repeating at alternating nodes every 135synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.
