Ciabattari, E. Mazzoni, and M. Rossi, Borgo a Mozzano, Italy, report their discovery of an apparent supernova on unfiltered CCD images obtained on Aug. 22.12 UT (when it was at mag 17.9; limiting mag 19.1) and on Aug. 26.01 (at mag 17.8; limiting mag 19.5) with a 0.5-m Newtonian telescope in the course of the Italian Supernovae Search Project. The new object is located at R.A. = 0h41m51s.40, Decl. = +32d59'23".4 (equinox 2000.0; astrometry with respect to UCAC-2 stars), which is 4" west and 5" south of the center of the galaxy UGC 442 = PGC 2504. Nothing is visible at this position on the digitized plates of the Palomar Sky Survey from 1989 Sept. 30 (F plate; limiting magnitude 20.3) and 1993 Sept. 16 (J plate; limiting mag 20.3) or on their own images from Sept. 2010 (limiting magnitude 18.8). This variable was designated PSN J00415140+3259234 when it was posted on the Central Bureau's TOCP webpage and is here designated SN 2011fq based on the spectroscopic report below. Additional magnitudes for 2011fq: Aug. 26.10, R = 17.2 +/- 0.3 (K. Sarneczky, 0.60-m Schmidt telescope, Konkoly Observatory, Hungary; three co-added 120-s images; position end figures 51s.39, 23".8); 26.792, 17.2 (J. Brimacombe, Cairns, Australia; red filter; position end figures 51s.38, 22".6); 26.961, 17.1: (Xavier Bros, Ager, Catalonia, Spain, 35-cm reflector + unfiltered ST8XME camera; position end figures 51s.49, 24".7, UCAC2 reference stars); 28.627, 17.7 (Brimacombe; infrared filter; position end figures 51s.57, 23".7); 30.289, 17.8 (Brimacombe; unfiltered; position end figures 51s.36, 23".5). Bros' image is posted at the following website URL: http://www.anysllum.com/SNUGC442.JPG. Brimacombe's image from Aug. 28 is posted at http://www.flickr.com/photos/43846774@N02/6091615239/. L. Magill, Queen's University, Belfast, and Isaac Newton Group; R. Kotak and S. Smartt, Queen's University, Belfast; and A. Pastorello, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that an optical spectrogram (range 330-900 nm) of PSN J00415140+3259234 = SN 2011fq was obtained at the William Herschel Telescope (+ ISIS spectrograph) by K. Maguire on Sept. 3.08 UT. The spectrum displays a prominent H_alpha component, with a distinct P-Cyg profile. The expansion velocity of H_alpha, as estimated from the blue edge of the absorption trough of this line, is about 9000 km/s, after correcting for the recession velocity of UGC 442 (4430 km/s, from Falco et al. 1998, The Updated Zwicky Catalogue; via the NED website). The Ca II near-infrared triplet is also present with a P-Cyg profile, as well as Na I D and Fe II lines. 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-II-plateau supernova, similar to SN 2004et at an epoch of about 35 days post-maximum (Sahu et al. 2006, MNRAS 372, 1315).
