The telescopic spectrum of NEA 2023 DZ2 compared two selected grain sizes of Norton County, our best fitting laboratory aubrite. The visible (0.45–0.70 μm) wavelength range (solid black line) of 2023 DZ2 was captured with the RAPTORS-I telescope, while the NIR (0.7–2.5 μm) range (black dots) was taken with the NASA Infrared Telescope Facility (IRTF) atop Maunakea, Hawaii. All spectra are set to unity at 1.5 μm.
