Full lunar eclipse - a "blood moon" as it will glow red
 I would suggest that "syzygy" is the Scrabble word of dreams. It means:  In astronomy, a syzygy /ˈsɪzɨi/ (from the Ancient Greek suzugos (σύζυγος) meaning, "yoked together") is a straight-line configuration of three celestial bodies.

Our three players coming up are the sun, the moon and earth - or more correctly:

sun ------  earth -------shadow ---> moon

Next Tuesday morning (15th) the moon will be eclipsed by Earth's shadow. This total lunar eclipse will be visible across the Western Hemisphere. The total phase will last 78 minutes, beginning at 3:06 a.m. EDT and ending at 4:24 a.m. EDT.

All set?
