Since the arrival of the Dawn space-craft [1] at Vesta the Visible and InfraRed Imaging Spectrometer (VIR) [2] has acquired hyperspectral images of Vesta’s surface in the wavelength range from 0.25 to 5.1μm. As part of the analysis of Vesta’s sur-face composition, a series of four quadrangle maps following the scheme of [3] have been produced show-ing the results derived from the spectroscopic analysis of the VIR data. We present the results of the spectro-scopic analysis achieved for the quadrangle V-23, which covers Vesta’s surface between 57°N - 57°S and 180° - 360°
