V : Direction of the center of Moon with respect to the center of Sun, measured counterclockwise from zenith, i.e. V = p - q. S.D. : Semi Diameter Dist. (d) : Angular distance between the centers of Sun and Moon. Mag. (D) : Magnitude = Percentage of diameter of Sun covered by Moon. D = (Semi Diameter of Sun + Semi diameter of Moon - d) / (Diameter of Sun) Obsc. : Obscuration = Percentage of surface area of Sun covered by Moon.
