Published: MPB 37, 127-130
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

Collaboration with L. Robinson (lead, MPB 29, 30-31)

Remeasured images using 2MASS conversions to calibrate sessions found the new solution, which is ambiguous. A period of 12.86 h is also possible.
