The mean diameter D = 147 ± 3 km of (106) Dione is derived from visual observations in Denmark, Germany and the Netherlands of the occultation of AGK 3 + 25°0989 on 1983 January 19. Photoelectric magnitudes are: B (1, 2°.4) = 8 m .51 ± 0 m .06 and B – V = 0 m .65 ± 0 m .07. The visual albedo is pv = .064. Constraints on the axis of rotation are derived from the observed elliptical contour.
