Photoelectric photometry and rotation periods of the asteroids 26 Proserpina, 194 Prokne, 287 Nephthys, and 554 Peraga
Abstract
We present the photoelectric observations of the asteroids 26 Proserpina, 194 Prokne, 287 Nephthys, and 554 Peraga, performed in the years 1977-1978 at the Astronomical Observatory of Torino. The resulting synodic rotation periods are, for Proserpina, 13 h13; Prokne, 15 h67; and Peraga, 13 h63. The period of Nephthys is possibly ∼7 h or the double. A tentative value for the phase coefficient of Peraga was found: 0.043 mag/degree.
