A total lunar eclipse occurred at the Moon’s descending node of orbit on Wednesday, December 9, 1992,{{cite web|title=December 9–10, 1992 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/1992-december-9|publisher=timeanddate|access-date=8 January 2025}} with an umbral magnitude of 1.2709. 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 3.9 days before perigee (on December 13, 1992, at 21:05 UTC), the Moon's apparent diameter was larger.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=1992&n=136|publisher=timeanddate|access-date=8 January 2025}}
According to Fred Espenak, this was the darkest eclipse in a decade, caused by the June 15, 1991 eruptions of Mount Pinatubo in the Philippines.[http://www.mreclipse.com/LEphoto/LEgallery1/LEgallery1.html Totality - 1992 Dec]
Visibility
The eclipse was completely visible over northern North America, Europe, Africa, and west, central, and north Asia, seen rising over much of North America and South America and setting over the eastern half of Asia.{{cite web|title=Total Lunar Eclipse of 1992 Dec 09|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1951/LE1992Dec09T.pdf|publisher=NASA|access-date=8 January 2025}}

Eclipse season
{{See also|Eclipse cycle}}
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.
