Light curves are presented for 11 asteroids based on photoelectric observations obtained in 1965 and 1978. From these light curves, light periods have been determined for seven of the asteroids: 26 Proserpina (either 10.60 or 13.11 hours), 2 Pallas (7.815 hours), 15 Eunomia (6.083 hours), 16 Psyche (8.39 hours), 32 Pomona (9.45 hours), 39 Laetitia (5.14 hours), and 675 Ludmilla (7.75 hours). The period of 16 Psyche obtained in the present work is noted to be different from those of van Houten-Groneveld and van Houten (1958). Observations of the remaining asteroids (1 Ceres, 14 Irene, 18 Melpomene, and 115 Thyra) are not sufficient to allow period determinations.
