Super Blue Blood Moon
Tomorrow night’s full moon is a rare event-it is a blue moon. What is the definition of a blue moon? When a month has two full moons within the same month, the second full moon is called a blue moon. Blue moons are not at all common; the last blue moon occurred in July of 2015. This brings to mind a popular phrase in the English language: “once in a blue moon.” This phrase is used to describe something happens infrequently, not a regular occurrence. Besides the rarity of experiencing a blue moon this month, tomorrow night’s full moon will be a supermoon. A supermoon or “super moon” is when the moon is the closest to the moon in its orbit. As such the moon appears larger and brighter in the nighttime sky. https://cdn.vox-cdn.com/thumbor/BAQb9XwhXnH16WH8GBFIdIRB_5o=/800x0/filters:no_upscale()/cdn.vox-cdn.com/uploads/chorus_asset/file/9789047/29_supermoon_size_1280.jpg Tomorrow night’s supermoon completes lunar trilogy -the full moons on December 3, 2017 and January 1, 2
