Solar eclipse of July 20, 1982
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.
A partial eclipse was visible for parts of the northern Soviet Union, northern Alaska, northern Canada, Greenland, and Northern Europe.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| June 21 Ascending node | July 6 Descending node | July 20 Ascending node |
| Partial solar eclipse Solar Saros 117 | Total lunar eclipse Lunar Saros 129 | Partial solar eclipse Solar Saros 155 |
