Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)Unitended collaboration with Robert D. Stephens (Center for Solar System Studies), who worked the asteroid three weeks earlier. He found the same period but an amplitude of 0.13 mag. This is not unexpected since his observations were at ~1° phase angle. Amplitude increases with increasing phase angle. |
