NOTES: |
Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)Collaboration with R.A. Koff (lead) et al. Only the PDO data are shown.
The asteroid was followed by the group over a large range of phase angles. It was possible to see the synodic period change over the course of the observations. This allowed approximate shape and spin axis modeling despite having data from only one apparition. |
