|Simulation of moon passing through Earth's shadow|
Oftentimes, the full moon appears coppery red during a total lunar eclipse because the dispersed light from all the Earth’s sunrises and sunsets falls on the face of the moon. Thus the term Blood Moon can be and is applied to any and all total lunar eclipses.
The simulation above displays 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 will be closest to the center of the shadow, making is darkest, and most red in appearance.
On April 15, 2014, the moon will pass through the southern part of the Earth's umbral shadow. It will be visible over most of the Western Hemisphere including east Australia, New Zealand, the Pacific ocean, and North and South America. In the western Pacific, the first half of the eclipse will occur before moonrise. In Europe and Africa, the eclipse will begin just before moonset. In North America, Mars will arguably be the most prominent object in the sky other than the moon, appearing 9.5° northwest of the moon. The bright start Spica will be 2° to the west, while Arcturus will be 32° north. Saturn will be 26° east and Antares 44° southeast.
The moon will enter Earth's penumbral shadow at 4:54 UTC and the umbral shadow at 5:58. Totality will last for 1 hour 18 minutes, from 7:07 to 8:25. The moment of greatest eclipse will occur at 7:47. At that point, the Moon's zenith will be approximately 1,900 miles southwest of the Galapagos Islands. The moon will leave the umbra shadow at 9:33 and the penumbra shadow at 10:38.
The umbral magnitude will peak at 1.2907. At that moment, the northern part of the moon will pass 1.7 arc-minutes south of the center of Earth's shadow, while the southern part will be 40.0 arc-minutes from center. Thus, the northern part of the moon will be noticeably darker. The moon's appearance will change significantly throughout the eclipse as the depth of the shadow changes.
