 In May 2010, a rotational lightcurve of "Mellena" was obtained from photometric observations by Robert Stephens at the Santana and GMARS observatories in California.Lightcurve analysis gave a well-defined rotation period of hours with a brightness variation of magnitude ().Subsequent observations were taken by Andrea Ferrero at the Bigmuskie Observatory in Mombercelli, Italy (), and Larry Owings at the Barnes Ridge Observatory in California in June 2010 (), as well as by Albino Carbognani Astronomical at the OAVdA Observatory in July 2010 ().
