Photometrics Studies of Asteroids. VII.

Abstract

Photoelectric light-curves of nine asteroids were derived with the 82-inch reflector of the Mc Donald Observatory. For three asteroids, light-curves were determined for the first time The main data are collected in Tables 1 and 2 and in the figures. The sense of rotation of Eunomia being retrograde was confirmed. A possible direct rotation for Laetitia was found. The period of (321), Florentina, a member of the Coronis family, was found to be as short as 2h52 .
