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

This is a tumbler. The secondary period for the given "primary" period is 52.05 h. However, a number of solutions are possible given the limited data set. The plots have been forced to the two periods.
