Family/Group: MB-Outer
Taxonomic Class: Ch
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)

Originally in MPB 27, 20-21 with P = 10.630, A = 0.24, U = 2. Remeasuring the images using 2MASS callibrations (see Warner, MPB 34, 113-119) gives a longer period and slightly higher ampliutde. The revised period agrees with Behrend who found 13.670 (U = 3) using data from 2007.
