A total [[lunar eclipse]] occurred at the Moon’s [[Lunar node|descending node]] of orbit on Sunday, April 2, 1950,<ref>{{cite web|title=April 2–3, 1950 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/1950-april-2|publisher=timeanddate|access-date=21 December 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 1.0329. 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 23 hours before [[Apsis|perigee]] (on April 3, 1950, at 20:00 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=1950&n=136|publisher=timeanddate|access-date=21 December 2024}}</ref>

This lunar eclipse was the third of a [[Tetrad (astronomy)|tetrad]], with four total lunar eclipses in series, the others being on [[April 1949 lunar eclipse|April 13, 1949]]; [[October 1949 lunar eclipse|October 7, 1949]]; and [[September 1950 lunar eclipse|September 26, 1950]].

This was the first total lunar eclipse of [[Lunar Saros 131]].

== Visibility ==
The eclipse was completely visible over much of [[Africa]], [[Europe]], and the western half of [[Asia]], seen rising over [[South America]] and setting over [[east Asia|east]] and [[northeast Asia]] and [[Australia]].<ref>{{cite web|title=Total Lunar Eclipse of 1950 Apr 02|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1901/LE1950Apr02T.pdf|publisher=NASA|access-date=21 December 2024}}</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]].
