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

Binary discovery. Collaboration with Robert D. Stephens, Center for Solar System Studies, Landers, CA. Follow-up to work in 2011. Other observers in 2003 and before did not report signs of being binary. The moderately elongated shape (a/b = 1.36 assuming a triaxial ellipsoid and equatorial view) is unusual for a small binary primary. Ds/Dp >= 0.20 0.02.
