A total lunar eclipse occurred at the Moon’s descending node of orbit on Monday, April 24, 1967, with an umbral magnitude of 1.3356. 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 16 hours after perigee (on April 23, 1967, at 20:00 UTC), the Moon's apparent diameter was larger.
This lunar eclipse was the first of a tetrad, with four total lunar eclipses in series, the others being on October 18, 1967; April 13, 1968; and October 6, 1968.
The Surveyor 3 probe was active on the Moon during this eclipse.A Solar Eclipse from the Moon APOD 2014 April 7
Visibility The eclipse was completely visible over northeast Asia, Australia, and much of the Pacific Ocean, seen rising over most of Asia and setting over North America and western and central South America.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) 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.
