Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico gave a "somewhat irregular" light curve with a period of 16.784 ± 0.001 hours and a brightness variation of 0.07 ± 0.01 in magnitude. When allowing for varying aspect angles and changes in mean motion, this result is consistent with past studies.[4]
