Lightcurves of 10 Hygiea, 241 Germania and 509 Iolanda.

LOPEZ-GONZALEZ M.J. and RODRIGUEZ E.

Abstract (from CDS):

The asteroids 10 Hygiea, 241 Germania and 509 Iolanda have been studied photometrically. From their lightcurves, synodic periods of 27.63±0.02, 15.51±0.01 and 12.72±0.02 hours, and amplitudes of 0.28mag, 0.17mag and 0.45mag, 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.
