October 2014 lunar eclipse
|Total lunar eclipse
October 8, 2014
Lomita, California, 10:56 UTC
The moon passes right to left through the Earth's shadow
A total lunar eclipse took place on 8 October 2014. It is the second of two total lunar eclipses in 2014, and the second in a tetrad (four total lunar eclipses in series). Other eclipses in the tetrad are those of April 15, 2014, April 4, 2015, and September 28, 2015.
Visibility and appearance
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 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.
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. 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 northern 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 October 7) 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.

The timing of total lunar eclipses are determined by its contacts:
- P1 (First contact): Beginning of the penumbral eclipse. The Earth's penumbra touches the Moon's outer limb.
- U1 (Second contact): Beginning of the partial eclipse. The Earth's umbra touches the Moon's outer limb.
- U2 (Third contact): Beginning of the total eclipse. The Moon's surface is entirely within the Earth's umbra.
- Greatest eclipse: The peak stage of the total eclipse. The Moon is at its closest to the center of the Earth's umbra.
- U3 (Fourth contact): End of the total eclipse. The Moon's outer limb exits the Earth's umbra.
- U4 (Fifth contact): End of the partial eclipse. The Earth's umbra leaves the Moon's surface.
- P4 (Sixth contact): End of the penumbral eclipse. The Earth's penumbra no longer makes contact with the Moon.
The eclipse is the one of four total lunar eclipses in a short-lived series at the descending node of the Moon's orbit.
