Lightcurves and pole determinations for the asteroids 69 Hesperia, 79 Eurynome and 852 Wladilena

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