dc.description.abstractReport the discovery of an apparent supernova in public images from the Catalina Sky Survey (CSS). SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011gi Sep. 21.27 0 32 43.00 +26 06 51.6 18.2 13".8 W, 13".6 S This variable was designated PSN J00324300+2606516 when it was posted on the Central Bureau's TOCP webpage and is here designated 2011gi based on the spectroscopic confirmation reported below. Additional unfiltered CCD magnitudes for 2011gi: June 10.44 UT, [19.5 (CSS); Sept. 23.151, 18.5 (Joseph Brimacombe, Cairns, Australia; position end figures 43s.00, 51".2; image posted at URL http://www.flickr.com/photos/43846774@N02/6177438626/); 23.246, 17.9 (R. A. Koff, Bennett, CO, USA; Meade 0.25-m f/10 Schmidt-Cassegrain reflector + Apogee AP-47p CCD camera; thirty stacked 60-s images; limiting mag 20.5; image scale 2"/pixel; position end figures 42s.97, 51".2, UCAC3 reference stars). 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 J00324300+2606516 = 2011gi was obtained on Sept. 27 UT by Marion 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 2011gi is a type-Ia supernova about 40 days after maximum light. The best-fit SNID templates are for 1991T-like type-Ia supernovae between 37 and 45 days post-maximum at z = 0.034....
