Abstract

We present observations of asteroids obtained in the period 1982-1989, comprising 107 complete or partial lightcurves of 59 different objects. These include additional data on "Photometric Geodesy" program asteroids (Weidenschilling et al. 1987, Icarus 70, 191-245), obtained to determine their shapes and pole orientations (Drummond et al. 1988, Icarus 76, 19-77), and targets of opportunity observed during the course of that program. We derive new or refined rotation periods for 16 asteroids, and estimates of, or constraints on, periods for 8 more. Data presented here and in Paper I (Weidenschilling et al. 1987) suggest that unusual lightcurves with unequal maxima and minima at large amplitudes are seen preferentially for M-type asteroids.
