A total lunar eclipse took place on April 15, 2014. It is the former of two total lunar eclipses in 2014, and the first in a tetrad (four total lunar eclipses in series). Subsequent eclipses in the tetrad are those of October 8, 2014, April 4, 2015, and September 28, 2015.
The eclipse was visible in the Pacific Ocean region, including Australia and New Zealand, as well as the Americas. The moon passed south of the center of the Earth's shadow. As a result, the northern part of the moon was noticeably darker than the southern part. It occurred during the ascending phase of the moon's orbit, part of lunar saros 122.

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.
