A partial [[lunar eclipse]] occurred at the Moon's [[Lunar node|ascending node]] of orbit on Thursday, April 25, 2013,<ref>{{cite web|title=April 25–26, 2013 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2013-april-25|publisher=timeanddate|access-date=15 November 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 0.0160. 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 1.8 days before [[Apsis|perigee]] (on April 27, 2013, at 15:50 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=2013&n=136|publisher=timeanddate|access-date=15 November 2024}}</ref>

Only a tiny sliver (1.48%) of the [[Moon]] was covered by the [[Earth|Earth's]] umbral shadow at maximum eclipse, but the entire northern half of the Moon was darkened from being inside the penumbral shadow. This was one of the shortest partial eclipses of the Moon in the 21st century, lasting 27 minutes. This was also the last of 58 umbral lunar eclipses in [[Lunar Saros 112]].

== Visibility ==
The eclipse was completely visible over [[Africa]], [[Europe]], and [[Asia]], seen rising over eastern [[South America]] and setting over [[Australia]].<ref>{{cite web|title=Partial Lunar Eclipse of 2013 Apr 25|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2013Apr25P.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]]. The first and last eclipse in this sequence is separated by one [[month#Synodic month|synodic month]].
