The (155140) 2005 UD lightcurve and rotational period from simultaneous observations
Résumé
Minor planet (155140) 2005 UD, a possible fragment of (3200) Phaethon and a target for Destiny+, was observed from two locations from Bucharest - Romania and Les Makes - Reunion, in the frame of an international campaign led by the Japanese colleagues. We have determined a rotational period of 5.231 +/- 0.034 hours with an amplitude of 0.38 magnitudes in agreement with previous reported values. We also report simultaneous observations from those two locations with overlapping lightcurves.
