Modern day solunar tables are credited to John Alden Knight, who in 1926 compiled a listing of natural influences that affect wildlife feeding behavior. Refining his theory to the gravitational effect of the sun and moon, Knight designated these as MINOR and MAJOR feeding periods. These designations describe the duration of predicted feeding events - not the intensity of feeding that might be observed. Minor Feeding Periods generally last 1.5 hours and Majors last 2.0 hours.
Minor Feeding Periods: Moonrise minor begins at moonrise and lasts 1.5 hours. Moonset minor begins approximately 1.0 hour before moonset and usually ends soon after the moon dips below the horizon.
Major Feeding Periods begin 1.0 hour before the moon reaches the highest point in its arc across the sky and continues for 1.0 hour after.
Many variables affect feeding; current (from tide or wind), changes in visible daylight (sunrise and sunset), local weather, moon phases, etc. Combine as many variables as possible for a better chance of an exceptional outing.
