It regularly reaches 11th magnitude in brightness, as on 11 January 2013, and 12 December 2017, when in favorable oppositions will be at magnitudes 10.7 and 10.4 respectively, very bright for a later-discovered minor planet.[citation needed]
Multiple photometric studies of this asteroid were performed between 1969 and 2003. The combined data gave an irregular light curve with a synodic period of 9.730 ± 0.004 hours and a brightness variation of 0.05–0.10 in magnitude.[4]
