Solar eclipse of November 25, 2011
A partial solar eclipse occurred at the Moon’s ascending node of orbit on Friday, November 25, 2011, with a magnitude of 0.9047. 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 Solar [eclipse of January 4, 2011|January 4], June 1, and July 1.
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.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| November 25 Ascending node | December 10 Descending node |
| Partial solar eclipse Solar Saros 123 | Total lunar eclipse Lunar Saros 135 |
