Stritzinger (Aarhus University), G. Valerin (INAF - OAPD), S Kumar (UVA), N. Morrell (LCO), C. Burns (Carnegie), and C. Pfeffer (VT), on behalf of the NUTS2 and POISE collaborations, report they obtained a visual-wavelength spectrum of supernova 2023xoo on November 17.1 UT with the Telescopio Nazionale Galileo (TNG) equipped with DOLORES. A rather noisy spectrum of the candidate reveals that it is most likely a type IIb about a week past explosion. Comparison with a library of template supernova spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) provides a reasonable match to the type IIb SN 2003bg at -15 days relative to peak brightness. Further spectroscopic observations are encouraged.
