Family/Group: MB-Outer
Taxonomic Class: Xk
Published: MPB 33, 58-62
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 was reported as 6.003 h in original MPB paper. A subsequent effort by Higgins et al. (2008, including PDO), found a better solution at 8.0074 h. The data from 2006 have been phased to that longer period.
