A partial solar eclipse will occur at the Moon's descending node of orbit on Monday, May 20, 2069,[1] with a magnitude of 0.0879. 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.

The partial solar eclipse will be visible for parts of the Antarctic Peninsula and extreme southern Chile and Argentina. This event will mark the beginning of Solar Saros 158.

Eclipse season

See also: Eclipse cycle

This eclipse is part of an eclipse 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 a fortnight. The first and last eclipse in this sequence is separated by one synodic month.

Saros 158

This eclipse is a part of Saros series 158, repeating every 18 years, 11 days, and containing 70 events. The series will start with a partial solar eclipse on May 20, 2069. It contains total eclipses from August 5, 2195 through August 13, 2808; hybrid eclipses on August 24, 2826 and September 3, 2844; and annular eclipses from September 15, 2862 through February 27, 3133. The series ends at member 70 as a partial eclipse on June 16, 3313. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of totality will be produced by member 10 at 4 minutes, 43 seconds on August 28, 2231, and the longest duration of annularity will be produced by member 57 at 6 minutes, 7 seconds on January 25, 3079. All eclipses in this series occur at the Moon’s descending node of orbit.[3]

Series members 1–8 occur between 2069 and 2200:
