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 2011hf Oct. 17.11 22 16 51.14 - 3 15 55.0 17.7 Nothing was visible at this position on a CSS image taken on Sept. 27.18 UT (limiting mag 20.0). L. Tomasella, A. Pastorello, S. Valenti, and S. Benetti, Istituto Nazionale di Astrofisica (INAF), Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrogram of 2011hf, obtained on Oct. 29.84 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC; range 360-810 nm; resolution 2.2 nm), is that of a type-Ia supernova at a redshift 0.054. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) suggests a normal type-Ia supernova about 10 after its B-band maximum brightness....
