Published: MPB 38, pending
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 previous period of ~15 h, determined with low amplitude lightcurves, appear to be the half period. The large amplitude in 2011 all but assures a bimodal solution and the longer period.
