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

Period analysis after remeasuing original images using 2MASS conversion for calibration was forced to fit near solution found in 2007 (MPB 35, 56-60).
By themselves, the data provide numerous solutions in the range of 4-12 hours. Using the half-period approach, a solution of 8.52 h is favored by the slightest of margins over 9.36 h.
