Solar eclipse of July 1, 2011
A partial solar eclipse occurred at the Moon’s descending node of orbit on Friday, July 1, 2011,[1][2] with a magnitude of 0.0971.[3] 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. It is the first new saros series to begin since saros 155 began with the partial solar eclipse of June 17, 1928. The eclipse belonged to Saros 156 and was number 1 of 69 eclipses in the series. Thus, the 2011 Jul 01 event was the first eclipse of the series.[4]
