Signs in the Moon

CNN - Blood moon returns; tetrad sequence of four continues
CNN reports: "Blood moon, Act II, opens soon in the heavens near you. And it will be bigger than Act I. If you live in the western half of the United States, you'll have a front-row seat on a lunar eclipse that will turn the moon a burnt reddish orange for about an hour Wednesday, creating the second blood moon in relatively short succession. [...] It will be the second in a sequence of four -- called a tetrad -- that are occurring in roughly six-month intervals. The next one will appear on April 4, 2015, and the last one on September 28, 2015."
