dc.description.abstractReport the Catalina Real-time Transient Survey's discovery of an apparent supernova in public images from the Mount Lemmon Survey. SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011bz Apr. 24.34 14 04 43.75 - 9 43 04.7 17.4 19" E, 26" S Note that Drake has revised the position from that used to automatically assign the provisional designation (PSN J14044453-0943160) that was given when this presumed supernova was posted on the Central Bureau's TOCP webpage; it is here designated SN 2011bz based on the spectroscopic report below. Additional unfiltered CCD magnitudes for 2011bz: Mar. 13.44 UT, [19.0 (Catalina Sky Survey; via Drake); Apr. 26.240, 17.5 (J. Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope _ STL11K camera at the New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 43s.60, 02".7); 26.661, 17.4 (Brimacombe; remotely using a 40-cm RCOS telescope + STL6K camera at the Macedon Ranges Observatory, Melbourne, Australia; position end figures 43s.62, 03".0). Brimacombe's first image is posted at website URL http://www.flickr.com/photos/43846774@N02/5657422949/; his second image is at http://www.flickr.com/photos/43846774@N02/5659643256/. G. H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, report that a spectrum (range 340-740 nm) of PSN J14044453-0943160 = SN 2011bz was obtained on Apr. 26 UT by M. Calkins with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross- correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2011bz is a type-Ia supernova a few days after maximum light. The velocity of the Si II 635.5-nm feature is estimated to be approximately 10700 km/s, using an estimated redshift of z = 0.0291, measured from host- galaxy emission lines....
