A total lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, January 9, 1982, with an umbral magnitude of 1.3310. 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 1.3 days after perigee (on January 8, 1982, at 11:30 UTC), the Moon's apparent diameter was larger.
