We present high-precision, time-resolved, visible and near-infrared photometry of the large (diameter ~ 2500 km) Kuiper belt object (136108) 2003 EL61. The new data confirm rapid rotation at period P = 3.9155 ± 0.0001 h with a peak-to-peak photometric range of ΔmR = 0.29 ± 0.02 mag and further show subtle but reproducible color variations with rotation. Rotational deformation of 2003 EL61 alone would give rise to a symmetric light curve free of color variations. The observed photometric… Expand
