A partial solar eclipse will occur at the Moon's ascending node of orbit on Saturday, January 26, 2047, with a magnitude of 0.8907. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
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]
It is a part of Saros cycle 151, repeating every 18 years, 11 days, containing 72 events. The series started with partial solar eclipse on August 14, 1776. It contains annular eclipses from February 28, 2101, through April 23, 2191, a hybrid eclipse on May 5, 2209, and total eclipses from May 16, 2227, through July 6, 2912. The series ends at member 72 as a partial eclipse on October 1, 3056. The longest duration of totality will be 5 minutes, 41 seconds on May 22, 2840.
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.
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.
21 eclipse events between June 21, 1982, and June 21, 2058
