Solar eclipse of October 22, 1911


An annular solar eclipse occurred at the Moon's descending node of orbit on Sunday, October 22, 1911, with a magnitude of 0.965. 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 5.75 days before apogee, the Moon's apparent diameter was larger.
Annularity was visible from the Russian Empire, China, French Indochina, Philippines, Dutch East Indies, Territory of Papua including the capital city Port Moresby, and British Western Pacific Territories. A partial eclipse was visible for parts of South Asia, Southeast Asia, East Asia, Australia, and Oceania.

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.
