The asteroids 10 Hygiea, 241 Germania and 509 Iolanda have been studied
From their lightcurves, synodic periods of 27.63
0.02 hours, and amplitudes of
have been deduced for 10 Hygiea, 241 Germania and 509 Iolanda, respectively.
The period found for 241 Germania is a significant revision from
one previously published, and we present a first indication of
pole orientation and shape.
A synodic period is obtained for 509 Iolanda.
The solution obtained for the sense of rotation, sidereal period, pole
orientation and shape properties for 10 Hygiea confirms previous results.
