Be it said that while the so-called "Supermoon" is a physical reality—a catchy word for when the full moon coincides with the Moon's perigee (smallest distance from Earth), making it an actual, factual ~14% bigger by area (from memory, correct me)—the so-called "blue Moon" is just an artifact of how we have come to divide the solar year into months of 30 or 31 (and, occasionally, 28 and 29) days each. The time between two full Moons being around 29.5 days, there are bound to be some months with two full Moons in them, and frankly it's hard to see that as something very special—about as special as a quarter starting on a Monday.
