Data Points: 153
Discovered: 1991-06-14  Palomar  E. F. Helin
Family/Group: Hungaria
Taxonomic Class: ES (Assumed)
Published: MPB Pending
NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

There were hints of a secondary period of about 13.8 h. Subtracting this period improved the RMS fit of the resulting lightcurve. The data were not conclusive. Detailed, high-precision observations are encouraged in the future.
