LIGHTCURVES, POLE DIRECTION AND SHAPE OF ASTEROIDS 121-HERMIONE, 150-NUWA, 236-HONORIA, 287-NEPHTHYS AND 377-CAMPANIA

Rotational periods, V lightcurves, B-V color indexes, rotation axis di rection and shape of five asteroids are presented. The B and V photoel ectric observations were carried out at Serra la Nave stellar station of Catania Astrophysical Observatory during March and August 1992 and May, July and September 1993. The synodic rotational periods determine d are: 121 Hermione (P=9(h).238+/-O-h.010), 150 Nuwa (P = 8(h).140+/-0 (h).005), 236 Honoria (P = 12(h).333+/-O-h.006), 287 Nephthys (P = 7(h ).580+/-0(h).004), 377 Campania (P = 8(h).48+0(b).01). No variation of the (B-V) color with the rotation appears for the asteroids observed. The determination of the pole direction and shape is performed by app lying the Amplitude-Magnitude method (Zappala et al., Asteroids, Comet s, Meteors, pp. 73-76. Uppsala Universitet, Reprocentralen, HSC, Uppsa la, 1983) to the data collected by us and to those reported in the lit erature.
