November 1957 lunar eclipse


A total lunar eclipse occurred at the Moon’s descending node of orbit on Thursday, November 7, 1957, with an umbral magnitude of 1.0305. 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 about 5.1 days after apogee, the Moon's apparent diameter was smaller.
This lunar eclipse was the last of an almost tetrad, with the others being on May 24, 1956 ; November 18, 1956 ; and May 13, 1957.

Visibility

The eclipse was completely visible over the eastern half of Asia, Australia, and Alaska, seen rising over the western half of Asia, Europe, and much of central and east Africa and setting over much of North America.

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.
