Abstract (from CDS):
F. 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. = 0:41:51.40, Decl. = +32:59:23.4 (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).
