A partial solar eclipse occurred on 25 November, 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 was the last of four partial solar eclipses in 2011, with the others occurring on January 4, 2011, June 1, 2011, and July 1, 2011.
