A total lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, October 18, 1967, with an umbral magnitude of 1.1426. 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 22 hours before apogee (on October 19, 1967, at 8:30 UTC), 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 24, 1967; April 13, 1968; and October 6, 1968.

Visibility

The eclipse was completely visible over northeast Asia, western North America, and the Pacific Ocean, seen rising over Asia and Australia and setting over eastern North America and South America.

Metonic series

This eclipse is the third of four Metonic cycle lunar eclipses on the same date, April 23–24, each separated by 19 years:

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will in nearly the same location relative to the background stars.
