A total solar eclipse will occur at the Moon's descending node of orbit between Thursday, April 10 and Friday, April 11, 2070, with a magnitude of 1.0472. 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.
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]
This eclipse is a part of Saros cycle 130, repeating every 18 years, 11 days, containing 73 events. The series started with partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular eclipses in the series. The series ends at member 73 as a partial eclipse on October 25, 2394. The longest duration of totality was 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occurs at the Moon’s descending node.[2]
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.
