Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico during 2010 gave a light curve with a period of 14.339 ± 0.001 hours and a brightness variation of 0.17 ± 0.02 in magnitude. The light curve shows three uneven minimums and maximums per rotation cycle.[2]
