CAPE CANAVERAL, Florida --- There will be a full "Blood Moon" total lunar eclipse during the morning of Saturday, April 4, 2015, which also happens to fall on the Second Day of Passover and Easter Saturday in 2015. The total lunar eclipse, when the moon is expected to turn into a dark-copper red Blood Moon, will start at 7:58 a.m. Eastern Daylight Time and ends at 8:03 a.m. Eastern Daylight Time.

As the above NASA map shows, the eclipse will be visible from all parts of the United States. Eastern North America and western South America can see beginning stages of the partial umbral eclipse low in the west before sunrise April 4, whereas middle Asia (India, western China, mid-Asian Russia) can view the ending stages of the partial umbral eclipse low in the east after sunset April 4. Greenland, Iceland, Europe, Africa and the Middle East won’t see this eclipse at all.
Total lunar eclipses are referred to as "Blood Moons" because they often appear dark red in color. For a total lunar eclipse to happen, the Moon must be full, which means it is directly opposite the Sun, with Earth in between. The reddish appearance of the Moon is caused by the Earth's atmosphere filtering out blue light from the sunlight that reaches the Moon. Full Moons in April are also known as a Pink Moon. But the time of year that a Full Moon appears does not affect its color. The April 2015 Full Moon will likely appear a dark-copper red to those who can view the full lunar eclipse.
