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

The 2011 data gives an ambiguous result of 3.3 or 6.6 h. Plots phased to both periods are given here. The data from 2007 can be fit to P ~ 3.2 h as a broad, monomodal solution.
