At dawn on April 15 from America a lunar eclipse will be seen, the first of a tetrad of "red moon"-a series of 4 eclipses, which occur approximately every six months and will be repeated only seven times in this century, NASA reported.
The action begins on Tuesday, when the full moon passes through the Earth's shadow amber, producing a midnight eclipse will be visible throughout North America. Another will follow the October 8, 2014, one more than the April 4, 2015 and another on September 28, 2015.
Total eclipses of the Moon, when the satellite crosses the umbra of the Earth, are rare and the last occurred on December 10, 2011. But the last time a series of four total lunar eclipses took place occurred in 2003 and 2004.
The phenomenon has been around throughout the history of many superstitions and references to prophecies of natural disasters of great magnitude.
For example, the book Four Blood Moons, published last year by the televangelist John Hagee, suggests a link between the tetrad and the Biblical prophecies about the end of the world.
The U.S. space agency Nasa said the eclipse will begin April 15 at 08:00 GMT when the edge of the moon enters the center of the shadow of the Earth, which is amber.
It is during this period that the moon looks from Earth, with a reddish color caused by sunlight and colored by their passage through the Earth's atmosphere, similar to the coloring that takes sunlight into the twilight.
The entire eclipse will take place over a period of 78 minutes beginning about an hour later and if weather conditions permit, the phenomenon can be observed in most of the Americas.
"During the twenty-first century, there will be 9 groups of tetrads; so tetrads describe as an event that occurs frequently in the current pattern of lunar eclipses, "says Espenak. "But this has not always been so. During the interval of three hundred years from 1600 to 1900, for example, there was tetrads "says Fred Espenak, who has been for a long time, an expert on eclipses, on Nasa
