November 1974 lunar eclipse
A total lunar eclipse occurred at the Moon’s descending node of orbit on Friday, November 29, 1974, with an umbral magnitude of 1.2896. 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 3.6 days before perigee, the Moon's apparent diameter was larger.
Visibility
The eclipse was completely visible over Asia, Australia, and Alaska, seen rising over much of Africa, Europe, and the Middle East and setting over much of North America and the eastern Pacific Ocean.Eclipse details

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.| November 29 Descending node | December 13 Ascending node |
| Total lunar eclipse Lunar Saros 125 | Partial solar eclipse Solar Saros 151 |
