N. Morrell, Las Campanas Observatory; P. Lopez and P. Lira, Universidad de Chile; and G. Pignata and F. Bufano, Universidad Andres Bello, report that an optical spectrogram (range 370-910 nm) of PSN J10525661-3256071 = SN 2012bu, obtained on Mar. 30.14 UT with the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory, shows it to be a type-II supernova. Adopting a recession velocity of 3274 km/s for NGC 3449 (Theureau et al., 1998, A.Ap. Suppl. 130, 333; via NED), the best fits to this spectrum found by GELATO (Harutyunyan et al. 2008, A.Ap. 488,383; publicly available at website URL https://gelato.tng.iac.es) is with spectra of evolved type-II-plateau supernovae.
