[1] The first precovery was taken at the U.S. Goethe Link Observatory in 1962, extending the asteroid's observation arc by 37 years prior to discovery.
[8] In October 2014, photometric observations by Italian astronomer Silvano Casulli gave a rotational lightcurve with a period of 2.78592±0.00003 hours and a brightness amplitude of 0.31 in magnitude (U=3-).
[6] Three weeks later, a second lightcurve was obtained at the U.S. Etscorn Campus Observatory in New Mexico, rendering a concurring period of 2.785±0.005 with an identical variation in brightness (U=3-).
[5] According to the survey carried out by NASA's space-based Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures 10.3 kilometers in diameter and its surface has an albedo of 0.202±0.038,[4] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 and calculates a diameter of 9.6 kilometers.
[3] A large-scale survey by Pan-STARRS (PS1) assigns an LS-type, an intermediary spectral type between the common, stony S-types and the rather rare and reddish L-type asteroids.
