October 1949 lunar eclipse


A total lunar eclipse occurred at the Moon’s ascending node of orbit on Friday, October 7, 1949, with an umbral magnitude of 1.2236. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring only about 15 hours before apogee, the Moon's apparent diameter was smaller.
This lunar eclipse was the second of a tetrad, with four total lunar eclipses in series, the others being on April 13, 1949; April 2, 1950; and September 26, 1950.

Visibility

The eclipse was completely visible over eastern North America, South America, and west Africa, and western Europe, seen rising over western North America and the eastern Pacific Ocean and setting over much of Africa, Europe, and west, central, and south Asia.

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.
