A partial solar eclipse occurred at the Moon's ascending node of orbit on Tuesday, July 20, 1982, with a magnitude of 0.4643. 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 was the third of four partial solar eclipses in 1982, with the others occurring on January 25, June 21, and December 15.

Solar eclipses of 1979–1982[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]
The partial solar eclipses on June 21, 1982 and December 15, 1982 occur in the next lunar year eclipse set.

Saros 155[edit]
This eclipse is a part of Saros series 155, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on June 17, 1928. It contains total eclipses from September 12, 2072 through August 30, 2649; hybrid eclipses from September 10, 2667 through October 2, 2703; and annular eclipses from October 13, 2721 through May 8, 3064. The series ends at member 71 as a partial eclipse on July 24, 3190. 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 14 at 4 minutes, 5 seconds on November 6, 2162, and the longest duration of annularity will be produced by member 63 at 5 minutes, 31 seconds on April 28, 3046. All eclipses in this series occur at the Moon’s ascending node of orbit.[2]

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).
