Solar eclipse of October 3, 2043


An annular solar eclipse will occur at the Moon's descending node of orbit on Saturday, October 3, 2043, with a magnitude of 0.9497. 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 4.8 days before apogee, the Moon's apparent diameter will be smaller.
It will be unusual in that while it is an annular solar eclipse, it is not a central solar eclipse. A non-central eclipse is one where the center-line of annularity does not intersect the surface of the Earth. Instead, the center line passes just above the Earth's surface. This rare type occurs when annularity is only visible at sunset or sunrise in a polar region.
While the path of annularity will be not visible from any land areas, a partial solar eclipse will be visible for parts of Madagascar, Antarctica, and southwestern Australia. This will be the first of 56 umbral eclipses in Solar Saros 154.

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.
