 In September 2006, a rotational lightcurve of "Naëma" was obtained from photometric observations by Collin Bembrick at the Mount Tarana Observatory , Australia, in collaboration with Bill Allen and Greg Bolt.Lightcurve analysis gave a relatively long rotation period of hours with a brightness variation of magnitude ().In December 2017, French amateur astronomer René Roy determined a lower-rated, tentative period of hours with an amplitude of magnitude ().
