NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

Radar observations by Benner et al. in 2000 and again in 2011 suggested a period of about 0.67 h. Pravec et al. (2000) reported a period of either 0.6658 or 1.3315 h. The PDO data from 2011 cannot be fit to either of these.
