NOTES: |
Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)Started as a target of opportunity.
Collaboration with Dan Coley (Center for Solar System Studies). There is a weak indication of a secondary period (~21.3 h). A plot of it is included here. It does not closely resemble the lightcurve that one would expect due to a satellite. Future observations are strongly encouraged. |
