The full moon has long been associated with any number of superstitions. While links with lunacy, violence, fertility, disasters, and the stock market have been thoroughly debunked, the possibility of a causative role in some arenas still remains a possibility. A lunar ranging study carried out using reflectors has long contended with the "Full-Moon Curse," a near-total fading of reflected signals during the full Moon. This Curse is real, and has now been explained.
