The first of four Blood Moons

◼ There has been a lot of interest recently in an upcoming series of lunar eclipses that begins April 15. These are usually described as "four blood moons" and taken by some to prophesy upcoming disasters.

The total lunar eclipse of April 15 will begin a so-called tetrad series of eclipses...

Astronomers rarely if ever use the term blood moon. When they do, they are usually using it as an alternate name for the Hunter's Moon, the full moon that follows the Harvest Moon, usually in late October. The Hunter's Moon, like the Harvest Moon, rises slowly on autumn evenings so that it shines through a thick layer of the Earth's atmosphere, and is colored red by Rayleigh scattering and air pollution....What is unusual about this month's lunar eclipse is that it is the first of a series of four total lunar eclipses in a row. Called a tetrad, such a series of four total eclipses in a row is a fairly rare event. The last such series happened in the years 2003 and 2004. It will only occur seven more times in the current century.What is unusual about this month's lunar eclipse is that it is the first of a series of four total lunar eclipses in a row.
