“On April 15, 2014, there will be a total lunar eclipse. It will be the first of four consecutive total eclipses in a series, known as a tetrad (the remaining three eclipses will take place on October 8, 2014, April 8, 2015, and September 28, 2015). It will be one of 8 tetrads during the 21st century AD. Like all eclipses, it is probable that the moon will appear to be a dark red color during the eclipse due to the refraction of sunlight through the Earth’s atmosphere. This is the same effect that causes sunsets to appear red.” (Source: Wikipedia)
