A partial solar eclipse occurred on 25 November, 2011.[1][2] 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 eclipse was visible across Antarctica in its summer 24-hour day sunlight, and New Zealand at sunset with less than 20% of the Sun obscured. Parts of the western Antarctic Peninsula experienced nearly 90% obscuration of the Sun, while South Africa and Tasmania experienced a very small partial eclipse. The eclipse belonged to Saros 123 and was number 53 of 70 eclipses in the series.

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.

Metonic series

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
