Template:Short description Script error: No such module "Unsubst". Template:Infobox lunar eclipse A total lunar eclipse occurred at the Moon’s descending node of orbit on Wednesday, October 8, 2014,[1] with an umbral 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 shadow is smaller. Occurring about 2.2 days after perigee (on October 6, 2014, at 5:40 UTC), the Moon's apparent diameter was larger.[2]

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

Background

Script error: No such module "Labelled list hatnote". 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.[3] 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 (opposition on 7 October[4]) during the eclipse, just over 1° from the eclipsed Moon. Shining at 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

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.[5]

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 selenelion, able to see both the sun and the eclipsed moon at the same time.[6]

The MESSENGER spacecraft from orbit at the 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.[7][8]

Eclipse season

Script error: No such module "Labelled list hatnote". 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.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[10] This lunar eclipse is related to two annular solar eclipses of solar saros 134.
