A partial [[lunar eclipse]] occurred at the Moon’s [[Lunar node|ascending node]] of orbit on Sunday, June 4, 2012,<ref>{{cite web|title=June 3–4, 2012 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2012-june-4|publisher=timeanddate|access-date=15 November 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 0.3718. A lunar eclipse occurs when the [[Moon]] moves into the [[Earth's shadow]], causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 about 1.1 days before [[Apsis|perigee]] (on June 3, 2012, at 9:15 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=2012&n=136|publisher=timeanddate|access-date=15 November 2024}}</ref>

== Visibility ==
The eclipse was completely visible over [[Australia]], [[Antarctica]], and the [[Pacific Ocean]], seen rising over [[east Asia]] and setting over [[North America|North]] and [[South America]].<ref>{{cite web|title=Partial Lunar Eclipse of 2012 Jun 04|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2012Jun04P.pdf|publisher=NASA|access-date=15 November 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]].
