Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado, during 2007 gave a light curve with a period of 6.551 ± 0.002 hours and a brightness variation of 0.05 in magnitude. This differs somewhat from a 2004 study that gave a period of 6.354 hours, but this difference may be explained by the small magnitude variation which tends to increase the randomizing effect of noise in the data.^[6]
