Family/Group: MB-Outer
Taxonomic Class: C
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, 6-7: P = 10.58, A = 0.35, U = 2. Remeasured images using 2MASS conversion to calibrate sessions found new results, which agree with results obtained from follow-up in 2009 (MPB 36, 109-116).
