A total [[lunar eclipse]] occurred at the Moon’s [[Lunar node|ascending node]] of orbit on Thursday, December 30, 1982,<ref>{{cite web|title=December 29–30, 1982 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/1982-december-30|publisher=timeanddate|access-date=6 January 2025}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 1.1822. 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 [[Umbra, penumbra and antumbra|shadow]] is smaller. Occurring only about 10.5 hours before [[Apsis|perigee]] (on December 30, 1982, at 22:00 UTC), the Moon's apparent diameter was larger.<ref>{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=1982&n=136|publisher=timeanddate|access-date=6 January 2025}}</ref>

This was a [[supermoon]] since [[perigee]] was on the same day. It was also a [[blue moon]], the second full moon of December for the [[eastern hemisphere]] where the previous full moon was on December 1.<ref name=natgeo_2018_01>{{cite web | url=https://www.nationalgeographic.com/science/article/super-blue-blood-moon-explained-space-astronomy-science | title=Rare 'Super Blue Blood Moon' Coming—First in 35 Years | date=29 January 2018 | last1=Fazekas | first1=Andrew | archive-url=https://web.archive.org/web/20180129221332/https://news.nationalgeographic.com/2018/01/super-blue-blood-moon-explained-space-astronomy-science/ | archive-date=29 January 2018 | website=[[National Geographic]]}}</ref> Since total lunar eclipses are also known as blood moons, this combination (which would not recur until [[January 2018 lunar eclipse|January 31, 2018]]<ref name=natgeo_2018_01/>) is known as a [[January 2018 lunar eclipse#"Super blue blood moon"|''super blue blood moon'']].<ref name=natgeo_2018_01/>

== Visibility ==
The eclipse was completely visible over [[north Asia|north]] and [[northeast Asia]], western and central [[North America]], and the central [[Pacific Ocean]], seen rising over [[northern Europe]], much of [[Asia]], and [[Australia]] and setting over eastern North America and western [[South America]].<ref>{{cite web|title=Total Lunar Eclipse of 1982 Dec 30|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1951/LE1982Dec30T.pdf|publisher=NASA|access-date=6 January 2025}}</ref>

== 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]].
