Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado, during 2008 gave a light curve with a period of 13.209 ± 0.001 hours and a brightness variation of 0.10 ± 0.01 in magnitude. This is in disagreement with a previous study reported in 2000 that gave a period estimate of 14.654 hours.[3]
