Data Points: 1833
Discovered: 2000-02-29  Socorro  LINEAR
Family/Group: NEA
Taxonomic Class: M
Published: MPB 36, 62-63
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 asteroid
Orbital Period: 42.201

Discovered by radar to be binary (Margot et al., Science 296, 1445-1448). Lightcurve observations by Pravec et al. (IAUC 7504) confirmed the discovery and found the orbital period. PDO data included two mutual events (occultations or eclipses).

These follow-up data refined the periods and found a slightly different shape to the curves. The data from two apparitions will help with modeling of the system.
