Phased rotational light curve for 2003 UY₁₁₇ using all the photometric data folded with a period of P = 12.376 h (upper panel) and P = 16.692 h (lower panel). The P = 12.376 h is our preferred solution. This double-peaked light curve with an amplitude of 0.36 mag indicates a highly nonspherical body with a presumable triaxial shape. Phase 0.0 corresponds to the moment of mid-occultation for the observed occultation chords.
