A totalsolar eclipse will occur at the Moon'sdescending node of orbit between Thursday, April 10 and Friday, April 11, 2070,[1] with amagnitude of 1.0472. 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 1.6 days beforeperigee (on April 12, 2070, at 17:50 UTC), the Moon's apparent diameter will be larger.[2]
The path of totality will be visible from parts ofSri Lanka, theAndaman and Nicobar Islands,Myanmar,Thailand,Cambodia,Laos,Vietnam,Yongxing Island, the southern tip ofTaiwan, and theNanpō Islands. A partial solar eclipse will also be visible for most ofAsia and parts ofAlaska,Hawaii, and westernCanada.

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 onMay 20, 2069 occurs in the previous lunar year eclipse set.

This eclipse is a part ofSaros series 130, repeating every 18 years, 11 days, and containing 73 events. The series started with a partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular or hybrid eclipses in this set. The series ends at member 73 as a partial eclipse on October 25, 2394. 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 was produced by member 30 at 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occur at the Moon’sdescending node of orbit.[5]

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 descending 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.

This eclipse is a part of the long periodinex cycle, repeating at alternating nodes, every 358synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.
