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 direction and shape of five asteroids are presented. The B and V photoelectric 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 determined are: 121 Hermione (P = 9h.238±0h.010), 150 Nuwa (P = 8h.140±0h.005), 236 Honoria (P = 12h.333±0h.006), 287 Nephthys (P = 7h.580±0h.004), 377 Campania (P = 8h.48±0h.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 applying the Amplitude-Magnitude method (Zappalà et al., Asteroids, Comets, Meteors, pp. 73–76. Uppsala Universitet, Reprocentralen, HSC, Uppsala, 1983) to the data collected by us and to those reported in the literature.
