Source-derived summary

A total lunar eclipse occurred at the Moon’s descending node of orbit on Saturday, April 13, 1968, with an umbral magnitude of 1.1116. 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 1.1 days before perigee (on April 14, 1968, at 7:50 UTC), the Moon's apparent diameter was larger.

This lunar eclipse was the third of a tetrad, with four total lunar eclipses in series, the others being on April 24, 1967; October 18, 1967; and October 6, 1968.

Visibility

The eclipse was completely visible over much of North America and South America, seen rising over northwestern North America and the central Pacific Ocean and setting over Europe, Africa, and the Middle East.

Editorial analysis

Why this record matters

“April 1968 lunar eclipse” is worth following because a concise public description often conceals a longer documentary argument. Here, April, lunar and eclipse provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 11, 2025. The linked authority identifier is Q4781883. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1968, 1116 and 1967.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
