M. Miluzio, S. Benetti, and F. Bufano, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova; A. Pastorello, Queen's University, Belfast; and G. Pignata, Universidad Andres Bello, on behalf of a larger collaboration, report on spectroscopic observations (range 340-800 nm) of 2010ls obtained on 2010 Dec. 31.32 UT with the EFOSC2 spectrograph mounted on the New Technology Telescope at the European Southern Observatory. The spectrum of 2010ls is that an evolved type-IIb supernova; from a comparison with a library of supernova spectra performed with the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488, 383; available at https://gelato.tng.iac.es/login.cgi), 2010ls is found to be most similar to SN 1993J at about two months after maximum light.
