[1] A first precovery was taken at Palomar Observatory in 1950, extending the body's observation arc by 21 years prior to its official discovery.
[10] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous C-type asteroids of 0.57 and calculates a diameter of 12.29 kilometers, based on an absolute magnitude of 13.28,[3] while according to preliminary data from the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid's surface has a much higher albedo of 0.158 and only measures 8.8 kilometers in diameter.
[4] Photometric observations by astronomer Brian D. Warner at the Palmer Divide Observatory in Colorado (716) during winter 2007–2008 were used to build a lightcurve, which gave a rotation period of 11.028±0.006 hours and a brightness variation of 0.24±0.02 in magnitude (U=3).
[7][a] The results concur with observations made by French amateur astronomers Stéphane Charbonnel and Laurent Bernasconi, and with analysed data from the Palomar Transient Factory Survey in 2004 and 2015, respectively (U=2/2).
