Man has long understood the effects of the gravitational pull of the moon, even beyond the obvious like the earth’s daily rising and falling ocean tides. This gravitational force also has a profound effect on living creatures. Deer hunters have long looked for a connection between the moon and deer activity. Initially, they looked for a connection between the various phases of the moon and deer movement. However, this connection never seemed to pan out for hunters and, despite continued efforts by some, was ultimately refuted by researchers.
In 1994, outdoor writer, Jeff Murray, penned the book, Moonstruck. In his book, the late Murray, asserted that it was not, in fact, moon phases that affected/predicted deer activity but, rather, it was the position of the moon. When you think about it, this makes more sense as the position of the moon better predicts the strength of the gravitational pull of the moon. Murray’s theory was based on various works including John Alden Knight’s Moon Up Moon Down, a book about his solunar tables. But, it was Murray who helped to isolate those times during the moon’s elliptical orbit around the earth that result in maximum gravitational pull. Known in astronomical circles as superior transit times and inferior transit times, this happens twice per orbit and is, essentially when the moon is directly overhead or underfoot.
