A partial solar eclipse occurred at the Moon's descending node of orbit between Thursday, December 3 and Friday, December 4, 1964, with a magnitude of 0.7518. 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 last of four partial solar eclipses in 1964, with the others occurring on January 14, June 10, and July 9.
A partial eclipse was visible for parts of Northeast Asia, southwest Alaska, and Hawaii.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) 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.
