Solar eclipse of August 15, 2091


A total solar eclipse will occur at the Moon's ascending node of orbit between Tuesday, August 14 and Wednesday, August 15, 2091, with a magnitude of 1.0216. 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 total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 3.3 days before perigee, the Moon's apparent diameter will be larger.
While the path of totality will not be visible from any landmasses, a partial solar eclipse will be visible for parts of Australia, Oceania, and Antarctica. This will be the last of 42 umbral eclipses of Solar Saros 127.

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.
