 Lightcurve analysis gave a rotation period of hours with a brightness amplitude of magnitude ().Alternative period determinations were made by Claes-Ingvar Lagerkvist () in March 1976, by astronomers at the Palomar Transient Factory () in January 2014, and by the Spanish group of asteroid observers, OBAS () in May 2015 ().In 2016, a modeled lightcurve gave a concurring sidereal period of hours using data from a large collaboration of individual observers (such as above).
