Family/Group: MB-Outer
Taxonomic Class: C
Published: MPB 37, 150-151
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

MPB 30, 61-64: P = 4.74, A = 0.06, U = 2-.

Remeasured images gave the slightly shorter, and ambiguous, period. P = 6.28 h cannot be ruled out. In fact, the fit to the longer period is better and so was used for the plot above.
