Solar eclipse of November 21, 1938
A partial solar eclipse occurred at the Moon's ascending node of orbit between Monday, November 21 and Tuesday, November 22, 1938, with a magnitude of 0.7781. 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.
A partial eclipse was visible for parts of Northeast Asia, Hawaii, and western North America.

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.| November 7 Descending node | November 21 Ascending node |
| Total lunar eclipse Lunar Saros 125 | Partial solar eclipse Solar Saros 151 |
