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

Follow-up to 2007 observations. A period of 14.62 h cannot be formally excluded. However, fitting the 2007 data to the shorter value strongly favors the adopted period of 29 h.
