Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado in 2007 gave a light curve with a period of 9.4146 ± 0.0002 hours and a brightness variation of 0.16 ± 0.02 in magnitude. This is reasonably consistent with independent results reported in 1983 (9.40h), 1993 (9.402h), and 2007 (9.334h).
