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

New Hungaria binary discovery. Collaboration with Dan Coley at Center for Solar System Studies. The bowed secondary lightcurve indicates a satellite that has a projected a/b ratio of ~2:1. The estimated size ratio is Ds/Dp 0.30 0.03. Observation list is for PDO only but plot includes data from both observatories.
