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

A spin axis model was possible after a third apparition and by using sparse data from UNSO-Flagstaff. The J2000 ecliptic coordinates are (90, -45). The negative latitude indicates that the asteriod is in retrograde rotation.
