A total [[lunar eclipse]] occurred at the Moon’s [[Lunar node|descending node]] of orbit on Wednesday, October 8, 2014,<ref>{{cite web|title=October 7–8, 2014 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/2014-october-8|publisher=timeanddate|access-date=16 November 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 1.1670. 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 2.2 days after [[Apsis|perigee]] (on October 6, 2014, at 5:40 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=2014&n=136|publisher=timeanddate|access-date=16 November 2024}}</ref>

This lunar eclipse is the second of a [[Tetrad (astronomy)|tetrad]], with four total lunar eclipses in series, the others being on [[April 2014 lunar eclipse|April 15, 2014]]; [[April 2015 lunar eclipse|April 4, 2015]]; and [[September 2015 lunar eclipse|September 28, 2015]].

== Background ==
{{main|Lunar eclipse}}
A lunar eclipse occurs when the Moon passes within Earth's [[umbra]] (shadow). As the eclipse begins, the Earth's shadow first darkens the Moon slightly. Then, the shadow begins to "cover" part of the Moon, turning it a dark red-brown color (typically - the color can vary based on atmospheric conditions). The Moon appears to be reddish because of [[Rayleigh scattering]] (the same effect that causes sunsets to appear reddish) and the refraction of that light by the Earth's atmosphere into its umbra.<ref>{{cite web|title=Visual Appearance of Lunar Eclipses|work=NASA|author=Fred Espenak|author2=Jean Meeus|name-list-style=amp|url=http://eclipse.gsfc.nasa.gov/LEcat5/appearance.html|access-date=April 13, 2014}}</ref>
The following simulation shows the approximate appearance of the Moon passing through the Earth's shadow. The Moon's brightness is exaggerated within the umbral shadow. The southern portion of the Moon was closest to the center of the shadow, making it darkest, and most red in appearance.

The planet [[Uranus]] was near [[Opposition (planets)|opposition]] (opposition on 7 October<ref>{{Cite web |url=http://in-the-sky.org/news.php?id=20141007_13_100 |title=Archived copy |access-date=19 April 2014 |archive-url=https://web.archive.org/web/20160326230844/https://in-the-sky.org/news.php?id=20141007_13_100 |archive-date=26 March 2016 |url-status=dead }}</ref>) during the eclipse, just over 1° from the eclipsed Moon. Shining at [[Magnitude (astronomy)|magnitude]] 5.7, Uranus should have been bright enough to identify in binoculars. Due to [[parallax]], the position of Uranus relative to the Moon varied significantly depending on the viewing position on the surface of Earth.

== Visibility and appearance ==
[[File:2014-10-08 Lunar Eclipse Sketch.png|thumb|right|NASA chart of the eclipse]]
The eclipse was completely visible over [[northeast Asia]], eastern [[Australia]], the [[Pacific Ocean]], and western [[North America]], seen rising over [[Asia]] and much of Australia and setting over North and [[South America]].<ref>{{cite web|title=Total Lunar Eclipse of 2014 Oct 08|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2014Oct08T.pdf|publisher=NASA|access-date=16 November 2024}}</ref>

The eclipse was visible in its entirety over the Northern Pacific. Viewers in North America experienced the eclipse after midnight on Wednesday, October 8, and the eclipse was visible from the [[Philippines]], western Pacific, Australia, [[Indonesia]], [[Japan]], and eastern Asia after sunset on the evening of October 8. Many areas of North America experienced a [[Lunar eclipse#Selenelion|selenelion]], able to see both the sun and the eclipsed moon at the same time.<ref name="selenelion">{{cite news|url=http://www.nbcnews.com/science/space/lunar-eclipse-provides-extra-twist-skywatchers-selenelion-n219586a|title=Lunar Eclipse Provides an Extra Twist for Skywatchers: Selenelion|first=Alan|last=Boyle|date=October 7, 2014|access-date=October 8, 2014|publisher=[[NBC News]]}}</ref>

The ''[[MESSENGER]]'' spacecraft from orbit at the planet [[Mercury (planet)|Mercury]] which was 107 million kilometers away from Earth at the time also observed the eclipse, making it the first lunar eclipse in history to be observed from another planet.<ref>{{cite web |title=Lunar Eclipse From Mercury |url=https://science.nasa.gov/resource/lunar-eclipse-from-mercury/ |publisher=NASA |access-date=20 April 2024}}</ref><ref name=EclipseReboost>{{cite web|url=http://www.planetary.org/blogs/emily-lakdawalla/2014/10100759-from-mercury-orbit-messenger.html |title=From Mercury orbit, MESSENGER watches a lunar eclipse|publisher= Planetary Society|date=October 10, 2014|access-date=January 23, 2015}}</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]].
