A partial solar eclipse occurred at the Moon's ascending node of orbit on Thursday, July 9, 1964, with a magnitude of 0.3221. 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 1964, with the others occurring on January 14, June 10, and December 4.
A partial eclipse was visible for parts of Canada, Greenland, and the eastern Soviet Union.

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. The first and last eclipse in this sequence is separated by one synodic month.
