Solar eclipse of May 11, 1975
A partial solar eclipse occurred at the Moon's descending node of orbit on Sunday, May 11, 1975, with a magnitude of 0.8636. 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.
A partial eclipse was visible for parts of North Africa, Europe, North Asia, Greenland, and northern Canada.

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.| May 11 Descending node | May 25 Ascending node |
| Partial solar eclipse Solar Saros 118 | Total lunar eclipse Lunar Saros 130 |
