LIGHTCURVES AND POLE DETERMINATIONS FOR THE ASTEROIDS 69-HESPERIA, 79-EURYNOME AND 852-WLADILENA

The results of photometric observations for three asteroids, 69 Hesper ia, 79 Eurynome and 852 Wladilena, are reported. The aim is to enlarge the set of asteroids for which the rotational and shape parameters ar e known. The lightcurves obtained during this study, along with lightc urves from other authors obtained during previous apparitions, are use d to derive pole and shape solutions, with the method described in De Angelis (Planet. Space Sci. 41, 285-290, 1993). For 69 Hesperia and 85 2 Wladilena this is the first pole and shape determination. For 79 Eur ynome an additional lightcurve, obtained during the 1993 opposition, e nable the previous solutions to be refined.
