 Based on observations taken on September 2004, Brian Warner at his Palmer Divide Observatory , Colorado, published an ambiguous period of and hours with an amplitude of and magnitude, respectively, depending on whether the period solution is derived from a monomodal or from a bimodal lightcurve ().Alternatively, Warner also gave a revised period of hours and an amplitude of magnitude for his other observation taken on December 2000.In February 2011, James Brinsfield at the Via Capote Observatory in California measured a period of hours with an amplitude of magnitude ().
