Solar eclipse of April 18, 1931
A partial solar eclipse occurred at the Moon's ascending node of orbit on Saturday, April 18, 1931, with a magnitude of 0.5107. 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.
