Based upon photometry observations between 1984 and 2007, it has a sidereal rotation period of 8.283065 h with an amplitude that can range up to 0.34±0.01 in magnitude. The lightcurve shows some shape irregularities. There are two valid solutions for the pole's ecliptic coordinates: (λ1, β1) = (38°, +75°) and (λ2, β2) = (237°, +73°).[3]
