D. Milisavljevic, Harvard-Smithsonian Center for Astrophysics (CfA); R. Fesen, Dartmouth College; A. Soderberg, CfA; and T. Pickering and P. Kotze, South African Astronomical Observatory, report that low-dispersion spectra (range 320-900 nm), obtained on Nov. 14.9 UT with the 10-m SALT telescope (+ RSS), show PSN J22571177-4323048 = SN 2011hs to be a type-IIb supernova. Comparison with spectra retrieved from the Supernova Spectrum Archive (SUSPECT; cf. website URL http://bruford.nhn.ou.edu/~suspect/index.html) shows a good match to the type-IIb supernova 2003bg at 15 days before maximum light (Hamuy et al. 2009, Ap.J. 703, 1612). Assuming a redshift of z = 0.00571 for the host galaxy, IC 5267 (Koribalski et al. 2004, A.J. 128, 16), the velocity at the minimum of the H-alpha absorption is measured to be approximately -18300 km/s.
