A partial solar eclipse occurred at the Moon's ascending node of orbit on Saturday, August 11, 2018, with a magnitude of 0.7368. 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 eclipse was visible in northeastern Canada, Greenland, Northern Europe, and northern Asia.

Visibility

Animated path.

The maximal phase of the partial eclipse was recorded in the East Siberian Sea, near Wrangel Island.

The eclipse was observed in Canada, Greenland, Scotland, most of the Nordic countries (Iceland, Norway, Sweden, Finland), Estonia, Latvia, practically throughout Russia (except for places southwest of the line roughly passing through Pskov, Moscow and Penza, and the most eastern places of the Far East), in Kazakhstan, Kyrgyzstan, Mongolia and China. During sunset, the eclipse was observed in North and South Korea.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) 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. The first and last eclipse in this sequence is separated by one synodic month.
