The Full Sturgeon Moon

◼ Traditionally, many Native American tribes named the full Moons to keep track of the seasons. Here are examples: Sturgeon Moon, Green Corn Moon, Wheat Cut Moon, Moon When All Things Ripen, and Blueberry Moon. - The Old Farmers Almanac

And, In 2013, the August moon will REALLY be a Blue Moon. That is, it will be the third full moon in the summer season which has four full moons in 2013. This is the original, correct definition of a Blue Moon. The definition about the second full moon in a month is a more recent simplified usage.
