A partial solar eclipse occurred on July 1, 2011. 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 is the first solar eclipse of saros series 156, only visible as a partial solar eclipse in a small area south of South Africa and north of Antarctica. At greatest eclipse, the magnitude is just 0.097.[1] It is the first new saros series to begin since saros 155 began with the partial solar eclipse of June 17, 1928.[2]

This eclipse is the third of four partial solar eclipses in 2011, with the others occurring on January 4, 2011, June 1, 2011 and November 25, 2011.
