Photometric observations of this asteroid at Palmer Divide Observatory in Colorado Springs, Colorado, during 2007 gave a light curve with a period of 9.262±0.001 hours and a brightness variation of 0.83±0.03 in magnitude.[7] A 2012 study based upon observations at the Organ Mesa Observatory in Las Cruces, New Mexico, during 2012 produced a conflicting period of 7.834±0.001 hours and a brightness variation of 0.17±0.02 in magnitude. Further study will be needed to resolve the discrepancies in period and amplitude.[8]
