Solar eclipse of March 21, 2099


An annular solar eclipse will occur at the Moon's ascending node of orbit between Saturday, March 21 and Sunday, March 22, 2099, with a magnitude of 0.93. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus. An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 2.1 days after apogee, the Moon's apparent diameter will be smaller.
The path of annularity will be visible from parts of the Auckland Islands, Chatham Island, and French Polynesia. A partial solar eclipse will also be visible for parts of eastern Australia, Oceania, Antarctica, Hawaii, Mexico, Central America, and the southwestern United States.

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.
