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 2011gs Sep. 23.46 4 21 09.99 +13 28 04.4 17.4 10".1 E, 3".7 S This variable was designated PSN J04210999+1328044 when it was posted on the Central Bureau's TOCP webpage and is here designated SN 2011gs based on the spectroscopic report below. Further CCD magnitudes for 2011gs: Mar. 29.15 UT, [19.4 (CSS); Sept. 29.39, 17.6 (CSS); Oct. 2.131, R = 18.9 (Federica Luppi, Varese, Italy; 0.36-m f/7.9 reflector + Bessell R filter; position end figures 10s.03, 04".5; CMC-14 catalogue reference stars; image posted at website URL http://www.astrogeo.va.it/pub/TOCP/PSN_J04210999+1328044.jpg). F. Bufano, Istituto Nazionale di Astrofisica (INAF), Osservatorio Astronomico di Catania; and S. Valenti and A. Pastorello, INAF, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrum of PSN J04210999+1328044 = SN 2011gs, obtained on Oct. 1.95 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC), shows it to be a type-Ia supernova. 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 30 after its B-band maximum (the deduced redshift is 0.027).
