 In June 2018, a rotational lightcurve of "Fatme" was obtained from 5 nights of photometric observations by Tom Polakis at the Command Module Observatory in Arizona.Lightcurve analysis gave a rotation period of hours with a brightness variation of magnitude ().The result supersedes previously reported period determinations of hours with an amplitude of magnitude by Robert Stephens at the Santana Observatory , California, in May 2001 (), hours with an amplitude of magnitude (tentative) by French amateur astronomer Laurent Bernasconi in December 2004 (), hours with an amplitude of magnitude (tentative) by French amateur astronomer René Roy in May 2012 (), and hours with an amplitude of magnitude by the Spanish group of asteroid observers, OBAS, in January 2016 ().
