Solar eclipse of September 4, 2100


A total solar eclipse will occur at the Moon's descending node of orbit on Saturday, September 4, 2100, with a magnitude of 1.0402. 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 2.5 days before perigee, the Moon's apparent diameter will be larger. This will be the last solar eclipse of the 21st century.
The path of totality will be visible from parts of Sierra Leone, Guinea, Côte d'Ivoire, Ghana, Togo, Benin, Nigeria, Cameroon, the Central African Republic, the Democratic Republic of the Congo, Rwanda, southwestern Uganda, Burundi, Tanzania, Mozambique, and Madagascar. A partial solar eclipse will also be visible for parts of Africa, Southern Europe, the Middle East, and Antarctica.

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.
