Supernova 2011gh in NGC 2405 = Psn J07321603+2554300

Report the discovery of an apparent supernova in public images from the Catalina Sky Survey. SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011gh Sep. 19.48 7 32 14.94 +25 54 14.6 18.3 12".5 E, 8".7 S Drake originally posted position end figures 16s.03, 30".0 on the Central Bureau's TOCP webpage, and the provisional designation PSN J07321603+2554300 was assigned to this varible; the designation SN 2011gh is assigned here, based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2011gh (unfiltered unless noted otherwise): Apr. 29.17 UT, [19.5 (Mount Lemmon Survey; via Drake); Sept. 20.476, 19.1 (Joseph Brimacombe, Cairns, Australia); 21.475, R = 19.0 (Brimacombe). Brimacombe's Sept. 20 image is posted at URL http://www.flickr.com/photos/43846774@N02/6167919130/; his Sept. 21 image is at http://www.flickr.com/photos/43846774@N02/6174516626/. S. Valenti, S. Benetti, L. Tomasella, and P. Ochner, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica; and A. Pastorello, Dipartimento di Astronomia, Universita di Padova, on behalf of a larger collaboration, report that a spectrogram (range 360-810 nm; resolution 2.2 nm) of PSN J07321603+2554300 = SN 2011gh, obtained on Sept. 26.10 UT, suggests that it is a type-Ib/c supernova. Cross-correlation with a library of supernova spectra via the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488, 383; available at URL https://gelato.tng.iac.es/login.cgi), suggests a type-Ib/c supernova a few weeks after B-band maximum....
