Solar eclipse of February 18, 2091
A partial solar eclipse will occur at the Moon's descending node of orbit on Sunday, February 18, 2091, with a magnitude of 0.6558. 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.
The partial solar eclipse will be visible for parts of Europe, North Africa, and Central Asia.

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.| February 18 Descending node | March 5 Ascending node |
| Partial solar eclipse Solar Saros 122 | Total lunar eclipse Lunar Saros 134 |
