 Well, George, these four full moons will appear 14% larger, 30% brighter, and make for some great observations in the sky. It's a calming effect for many people, and no doubt beautiful. The average distance of the moon during this time is some 224,000 miles from the Earth, but the closest one of the year is that super full moon on October the 17th, when that full super hunter's moon comes within some 221,000 miles of the Earth.
