Visible spectrum of asteroid 2023 FY₃ obtained with the 10.4 m GTC on the night of March 28, 2023. Error bars correspond to the standard deviation of the mean. The gray hatched region accounts for the three best taxonomical fits (DeMeo et al. 2009), in order of increasing χ²: Sq, Sr, and S-type. We also show the taxon corresponding to V-types (basaltic asteroids), in green, for comparison purposes.
