When is the next blood moon for 2015?

Answer 1

The next total lunar eclipse will be the evening of September 27, 2015 as seen from the Americas, or around midnight in Western Europe. It will be easily visible in western Europe, western Africa, all of South America and the eastern 2/3 of North America.

HOWEVER...

The term "blood moon" was rarely used before a Texas preacher named John Hagee wrote a book "Four Blood Moons" in 2013. Lunar eclipses will cause the Moon to turn red or orange, as sunlight refracted (bent) in the Earth's atmosphere and into the dark area of the Earth's umbra, or shadow. Lunar eclipses are absolutely predictable, happening like clockwork as the Earth and Moon travel in their respective orbits. There are generally two lunar eclipses per year, but because the alignment isn't perfect, sometimes we get two partial or penumbral eclipses instead of one total eclipse. Infrequently, we'll experience two or even three total lunar eclipses in sequence; a few times a century, we'll see a "tetrad" of four total eclipses in a row.

John Hagee observed that these four total lunar eclipses in a row were going to approximately coincide with the dates of the Jewish holidays of Passover and Yom Kippur, and inferred that this was a cosmic "sign from God" that the end times were approaching.

Now, it isn't unusual for Passover and Yom Kippur to coincide with lunar eclipses. Lunar eclipses can only occur at the full moon, and the Hebrew calendar is a luni-solar one; Passover and Yom Kippur are defined as being within a day or two of the full moon every year. It isn't even unheard of for the unusual "tetrad" of four total lunar eclipses might coincide with Jewish holidays; it happened in the late 1940's, for example.

So, go ahead and enjoy the sight of the probably-copperish Moon at the total lunar eclipse the evening of September 27, two months from now, four days AFTER Yom Kippur.
