A totalsolar eclipse will occur at the Moon'sascending node of orbit between Thursday, April 9 and Friday, April 10, 2043,[1] with amagnitude of 1.0095. 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 22 hours beforeperigee (on April 10, 2043, at 17:10 UTC), the Moon's apparent diameter will be larger.[2]
It will be unusual in that while it is a total solar eclipse, it is not a central solar eclipse. Anon-central eclipse is one where the center-line of totality does not intersect the surface of the Earth (when thegamma is between 0.9972 and 1.0260). Instead, the center line passes just above the Earth's surface. This rare type occurs when totality is only visible at sunset or sunrise in a polar region.
This will be the first of 43 umbral eclipses inSolar Saros 149.
The eclipse will be seen fully from Russia'sKamchatka Peninsula,Magadan Oblast and on the north-east ofYakutia (in the morning on April 10 local time). It will be visible partially throughout northeasternRussia, inCanada,Greenland,Svalbard andIceland. It will be also partially visible from the western partUnited States includingAlaska,Hawaii, and theNorth Pacific.
Settlements of total phase:Evensk,Omsukchan,Palana,Seymchan andZyryanka.

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 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]

Themetonic 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.

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.
