dc.description.abstractReport the discovery of an apparent supernova in unfiltered Mount Lemmon Survey (MLS) images: SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011iz Nov. 30.26 3 21 36.48 +22 33 46.1 17.6 0".1 W, 15".3 S The variable was designated PSN J03213648+2233461 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011iz based on the spectroscopic confirmation reported below. Further CCD magnitudes for 2011iz (unfiltered unless noted otherwise): Oct. 20.43 UT, [20.5 (MLS); Dec. 1.475, 18.2 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera + luminance filter at New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 36s.49, 45".7; image posted at website URL http://www.flickr.com/photos/43846774@N02/6438246969/); 4.323, 17.2 (L. Elenin, Lyubertsy, Russia; three 300-s images remotely taken at the ISON-NM Observatory near Mayhill with a 0.45-m f/2.8 telescope + KAF09000 CCD chip; position end figures 36s.47 +/- 0".1, 46".6 +/- 0".1; reference stars from the NOMAD catalogue; stars; limiting mag about 19.8; image posted at URL http://spaceobs.org/images/TOCP/PSNJ03213648+2233461-20111204.png); 6.948, 17.8 (S. Foglia and G. Galli, Pogliano Milanese, Italy; 0.28-m f/6.8 Schmidt- Cassegrain reflector + ST8XME camera; position end figures 36s.49, 46".3; UCAC-2 reference stars); 10.988, 18.9 (Federica Luppi, Varese, Italy; 0.35-m f/7.9 reflector + Bessell-R filter; position end figures 36s.47, 46".4; reference stars from CMC-14 catalogue). L. Tomasella, S. Benetti, A. Pastorello, S. Valenti, and F. Bufano, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrogram of PSN J03213648+2233461 = SN 2011iz, obtained on Dec. 15.93 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 350-820 nm; resolution 2.4 nm), shows it to be a type-Ia supernova. The best fit to this spectrum found by GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; available at website URL https://gelato.tng.iac.es/login.cgi) suggests that 2011iz is similar to SN 1989B (Barbon et al. 1990, A.Ap. 237, 79) about two weeks after maximum light, if a redshift of 0.038 is assumed for the host galaxy....
