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 revision from the previously reported period of 38.6 hours. The data from the 2012 apparition favor a period of near 20 or 40 hours. The best fit near these for 2007 was 20.3 h.
