ROTATIONALLY RESOLVED VISIBLE AND NEAR-INFRARED SPECTROSCOPIC CHARACTERIZATION OF ASTEROID (223) ROSA

We present the results of our April, 2023 spectroscopic observation campaign in the form of four quarter-phase visible and near-infrared rotationally resolved spectra of the asteroid (223) Rosa as well as a rotationally combined median spectrum. (223) Rosa was confirmed to be an X-type asteroid under the Bus-DeMeo taxonomic system with a ~7.7%/𠜇m hemispherical variation caused by potential grain size or topological differences. Rosa's closest meteorite analog was found to be a weighted linear spectral mixture between 2 primitive meteorite types: a <125 𠜇m, relatively fresh sample of the meteorite Tagish Lake (10 %), and a 45-90 𠜇m sample of the meteorite Tarda (90 %) through chi-squared analysis. Similarities were found with both spectra, but albedo and density measurements favor Tagish Lake.
