Photometric observations of 74 asteroids obtained with the Carlsberg Automatic Meridian Circle between January 1990 and December 1993 are presented. The data from individual asteroid apparitions have been fitted by phase curves based on the standard HG magnitude system. Statistics on mean G-values for different types of asteroids are presented. A few new determinations of asteroid rotation periods are presented. In addition, we analyse magnitude-aspect relations, and derive ellipsoidal shape models for some asteroids.
