Abstract • We determine the rotation periods, lightcurve amplitudes, and H-G parameters for three potentially binary Hilda asteroids. We measured a rotation period of 40.06 ± 0.06 h, amplitude of 0.82 ± 0.02 mag, Hr’ = 11.74 ± 0.01 mag, and Gr’ = 0.73 ± 0.07 for 3923 Radzievskij. For (307321) 2002 QA123, we measure a rotation period of 26.502 ± 0.006 h, an amplitude of 0.79 ± 0.06 mag, HR = 15.12 ± 0.01 mag, and GR = 0.71 ± 0.04. For (445068) 2008 SE268, we determine a rotation period of 7.903 ± 0.003 h and amplitude of 1.1 mag, with HR = 15.40 ± 0.03 mag and GR = 0.44 ± 0.14.
