dc.description.abstractReport the discovery of an apparent supernova in public images from the Siding Spring Survey (SSS). SN 2012 UT R.A. (2000.0) Decl. Mag. Offset 2012bu Jan. 16.69 10 52 56.61 -32 56 07.1 18.4 37".2 E, 27".7 S The variable was designated PSN J10525661-3256071 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012bu based on the spectroscopic confirmation reported below. Further CCD magnitudes for 2012bu: 2010 June 26.40 UT, [19.2 (SSS); 2012 Jan. 18.436, 17.9 (Joseph Brimacombe, Cairns, Australia; 51-cm RCOS telescope + STL11K camera + luminance filter at the New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 56s.53, 07".7); 18.45, 18.3 (L. Elenin, Lyubertsy, Russia; remotely taken at the ISON-NM Observatory near Mayhill with a 0.45-m f/2.8 telescope; position end figures 56s.52, 07".7; UCAC3 reference stars; limiting mag about 20.0). The image by Brimacombe is posted at the following website URL: http://www.flickr.com/photos/43846774@N02/6722843895/. 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.
