Abstract
An observational survey of rotation lightcurves for 12 members of the Koronis asteroid family was conducted during the period 1987-1994, wit h the goal of establishing a sufficient data set to allow analysis of the distribution of their spin-axis orientations. A total of 137 indiv idual lightcurves were obtained using photoelectric and CCD photometry techniques for asteroids 158, 167, 208, 243, 263, 277, 311, 321, 462, 534, 720, and 1223. All these data have been calibrated to the Johnso n V magnitude system. Forty-eight new composite lightcurves for the 12 target asteroids are presented, and new or refined rotation periods f or 11 of them are reported. (C) 1996 Academic Press, Inc.
