Data Points: 934
Discovered: 1993-07-16  Palomar  E. F. Helin
Family/Group: Hungaria
Taxonomic Class: ES (Assumed)
Published: MPB 38, pending
ACM 2005 Proceedings
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

First Hungaria binary discovery at PDO. The orbital plot shows some "mutual events", which are due to occultations and/or eclipses involving the satellite.
