dc.description.abstractReport the discovery of an apparent supernova in unfiltered Catalina Sky Survey (CSS) images: SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011ig Nov. 17.21 1 05 54.65 -12 20 48.6 16.9 0".7 W, 3".7 S The variable was designated PSN J01055465-1220486 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011ig based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011ig: Oct. 30.28 UT, [17.5 (CSS); Nov. 20.316, 17.5 (J. Brimacombe, Cairns, Australia; luminance filter; position end figures 54s.65, 50".2; image posted at website URL http://www.flickr.com/photos/43846774@N02/6375756043/). S. Valenti, A. Pastorello, S. Benetti, L. Tomasella, F. Bufano, and P. Ochner, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrogram of PSN J01055465-1220486 = SN 2011ig, obtained on Nov. 20.89 UT with the 1.82-m Copernico Telescope (+ AFOSC; range 340-790 nm, resolution 2.2 nm), suggests that it is a 1991T-like type-Ia supernova. Cross-correlation with a library of supernova spectra via the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2011ig is similar to SN 1999aa (Garavini et al. 2004, A.J. 128, 387) around maximum light. Assuming a redshift of z = 0.065, the ejecta velocity deduced from the minimum of the Si II 635-nm line is about 13500 km/s....
