Super blood moons are rare, occurring when a total lunar eclipse coincides with a 'supermoon,' the term for a new or full moon that closely coincides with its perigee, the closest point to Earth in its monthly orbit.
The resulting 'blood Moon' appears larger, as it is closer to the Earth, and redder, because it is lit by light refracted through the Earth's atmosphere.
The phenomenon has happened only five times since 1900, and was last observed in 1982; it will not return until 2033.
