Data Points: 192
Discovered: 1982-09-19  Palomar  E. F. Helin
Family/Group: Hungaria
Taxonomic Class: ES (Assumed)
Published: MPB 37, 57-64
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

Using sparse data and previous lightcurves from PDO and others, a spin axis was modeled: (195, 0, 2.889026). This a very preliminary solution.
