A total [[lunar eclipse]] occurred at the Moon’s [[Lunar node|descending node]] of orbit on Friday, November 29, 1974,<ref>{{cite web|title=November 29–30, 1974 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/1974-november-29|publisher=timeanddate|access-date=4 January 2025}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 1.2896. 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 about 3.6 days before [[Apsis|perigee]] (on December 3, 1974, at 6:40 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=1974&n=136|publisher=timeanddate|access-date=4 January 2025}}</ref>

== Visibility ==
The eclipse was completely visible over [[Asia]], [[Australia]], and [[Alaska]], seen rising over much of [[Africa]], [[Europe]], and the [[Middle East]] and setting over much of [[North America]] and the eastern [[Pacific Ocean]].<ref>{{cite web|title=Total Lunar Eclipse of 1974 Nov 29|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1951/LE1974Nov29T.pdf|publisher=NASA|access-date=4 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]].
