A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Friday, November 18, 1994, with an umbral magnitude of −0.2189. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. 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. Occurring only about 1.5 hours after apogee (on November 18, 1994, at 5:05 UTC), the Moon's apparent diameter was smaller.
Visibility The eclipse was completely visible over North America and western and central South America, seen rising over northeast Asia, eastern Australia, and the western and central Pacific Ocean and setting over eastern South America, west and north Africa, and Europe.

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.
