1. A golf ball having a generally spherical outer surface and a center, the outer surface being provided with a plurality of dimples, at least some of the dimples having a surface with an elliptical cross section which is a portion of an ellipse defined by the equation: X2/A2+(Y-k)2/B2=1where X is a coordinate on an X axis which extends perpendicularly to a radial line from the center of the ball to the center of the ellipse, Y is a coordinate on a Y axis which is aligned with said radial line, A is one-half of the major axis of the ellipse which is aligned with said X axis, B is one-half of the minor axis of the ellipse which is aligned with said Y axis, and K is the distance along the Y axis between the center of the ellipse and the center of the golf ball.
