dc.description.abstractReport the discovery of an apparent supernova in public images from the Catalina Sky Survey; it was confirmed in images obtained with the Siding Spring Survey (SSS). SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011ds May 13.42 20 02 20.93 -20 13 13.4 16.6 6" W, 17" N The variable was designated PSN J20022093-2013134 when posted at the Central Bureau's TOCP webpage and is here designated SN 2011ds based on the spectroscopic confirmation that is detailed below. Further magnitudes for 2011ds: Apr. 11.74 [19.0 (SSS); May 14.69, 16.6 (SSS); 15.721, 16.6 (Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia, 30-cm telescope + STL6K camera + red filter; position end figures 20s.92, 12".8). Brimacombe's image is posted at URL http://www.flickr.com/photos/43846774@N02/5724709574/. S. Valenti and S. Benetti, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a low-signal-to-noise spectrogram (range 330-750 nm; resolution 1.5 nm) of PSN J20022093-2013134 = SN 2011ds, obtained on June 26.43 UT with the European Southern Observatory's New Technology Telescope (+ EFOSC2), is consistent with that of a type-II supernova. The spectrum indeed shows strong hydrogen H-alpha at 669.1 nm, mainly in emission with a full-width-at-half-maximum of about 7400 km/s....
