Title: Tracking system

A system of tracking the sun each day of the year with compensation for changes in time of sunrise and time of sunset as well as sun declination on a day to day basis, declination being under control of a crank that makes one revolution per year. The equation of time is under control of a cam that also revolves once a year and resets the clock to reflect solar rather than mean solar time in order to properly follow the sun. The position of sun acquisition and loss are a function of the declination and the time is a function of the clock corrected via the cam for equation of time. Thus, when the declination is reset each day, it sets the position of acquisition and loss while the clock, now set for the change due to the equation of time, determines the time of acquisition and loss.
