Spectroscopy of (1917) Cuyo. The spectra were collected on July 25, 2011 with the ESO NTT telescope. All spectra are normalized to unity at 5500 Å. The panels on the left show the raw extracted spectra, and a binned version overplotted. The panels on the right include the NTT spectra resampled at the wavelengths used in the Bus-DeMeo taxonomy (Bus & Binzel 2002; DeMeo et al. 2009)and compared with those classes that most closely match Cuyo. The spectra are quite consistent with either S or Sv types, and no robust indication of compositional variations is evident. We also include the mean spectrum for the Sr type from the Bus-DeMeo taxonomy, just to highlight how distinctive this class is from S/Sv types, even within this wavelength range. Table 4 gives additional information related to the observing geometry on this date (IDs 11-13).
