 In June 2011, a rotational lightcurve of "Rosalinde" was obtained from photometric observations by Meaghann Stoelting and David DeGraffat at the Stull Observatory of the Alfred University in New York.Lightcurve analysis gave a rotation period of hours with a brightness variation of magnitude ().Assuming an equatorial view, the observers also constrained the object's elongated shape to be at least 36% longer than wide.
