LONG NIGHTS MOON:
According to folklore, tonight’s full moon is called the Long Nights Moon. The reason is obvious: December nights are long (in the northern hemisphere).
Tonight’s moon also happens to be the highest-soaring full moon in 18 years. As seen from most parts of the USA and Europe, it will be above the horizon for more than 15 hours–a long night indeed.
