 The result supersedes a tentative period determination by French amateur astronomer René Roy from May 2007 ().Additional observation by the Spanish OBAS group gave a period of hours with an amplitude of magnitude ().In 2016, a modeled lightcurve gave a concurring sidereal period of hours using data from the Uppsala Asteroid Photometric Catalogue, the Palomar Transient Factory survey, and individual observers (such as above), as well as sparse-in-time photometry from the NOFS, the Catalina Sky Survey, and the La Palma surveys .
