A partial solar eclipse occurred at the Moon's descending node of orbit on Friday, October 21, 1949, with a magnitude of 0.9638. 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.
