Visible spectra of asteroid 2023 DZ2 obtained with the 10.4 m Gran Telescopio Canarias on the night of 17 March 2023 (dark blue) and on the night of 20 March 2023 (orange). Error bars correspond to the standard deviation of the mean for the March 17 data. The error bars for the 20 March data are much smaller and are contained within the larger ones. The grey hatched region accounts for the three best taxonomic fits in order of increasing χ2: T-, D-, and Xe-types.
