Passage: A total lunar eclipse occurred on January 31, 2018. The Moon was near its perigee on January 30 and as such may be described as a "supermoon". The previous supermoon lunar eclipse was in September 2015.As this supermoon was also a blue moon (the second full moon in a calendar month), it was referred to as a "super blue blood moon"; "blood" refers to the typical red color of the Moon during a total lunar eclipse. This coincidence last occurred on December 30, 1982 for the eastern hemisphere, and otherwise before that on March 31, 1866. The next occurrence will be on January 31, 2037, one metonic cycle (19 years) later.
