An annular solar eclipse will occur on Wednesday, May 21, 2031. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring only 3.8 days before apogee (Apogee on May 25, 2031), the Moon's apparent diameter will be smaller.

Solar eclipses 2029–2032 edit

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]

Note: Partial solar eclipses on January 14, 2029 and July 11, 2029 occur on the previous lunar year eclipse set.

Solar eclipse series sets from 2029 to 2032

Saros 138 edit

It is a part of Saros cycle 138, repeating every 18 years, 11 days, containing 70 events. The series started with partial solar eclipse on June 6, 1472. It contains annular eclipses from August 31, 1598 through February 18, 2482 with a hybrid eclipse on March 1, 2500. It has total eclipses from March 12, 2518 through April 3, 2554. The series ends at member 70 as a partial eclipse on July 11, 2716. The longest duration of totality will be only 56 seconds on April 3, 2554.

Series members 25–35 occur between 1901 and 2100:

Metonic series edit

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 descending node.^[2]

Octon series with 21 events between May 21, 1993 and August 2, 2065
