[21]: 23 Photometric observations of the asteroid by American photometrist Frederick Pilcher from his Organ Mesa Observatory (G50) in New Mexico during 2016−17 showed an irregular lightcurve with a synodic rotation period of 13.868 hours and an amplitude of 0.11 in magnitude (U=3).

[17][c] This result is in good agreement with two previous observations by Robert Stephens, and by Cyril Cavadore and Pierre Antonini who measured a period of 13.82 hours and a brightness variation of 0.12 and 0.05, respectively (U=3/2-).

[16][15] Other rotational lightcurves obtained by Alan Harris (10 h; 1980),[13] by Italian (10.47 h; 2000),[14] and Swiss/French astronomers (13.82 h; 2005),[16] and at the Colgate University (26.53 h; 2001),[18] are of poor quality (U=n.a./1/1/1).

[8][9][11][12] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.058 and calculates a diameter of 162.85 kilometers based on an absolute magnitude of 7.65.

[b] In New Zealand, on 18 February 2002, it occulted the star TYC 7299-00684 in the constellation of Centaurus for approximately 12.7 seconds during which a drop of 2.1 in magnitude was to be expected.
