Green; Hoffman Lab 209; Harvard University; 20 Oxford St.; Cambridge, MA 02138; U.S.A. e-mail: cbatiau@eps.harvard.edu (alternate cbat@iau.org) URL http://www.cbat.eps.harvard.edu/index.html Prepared using the Tamkin Foundation Computer Network SUPERNOVA 2011ix IN MCG +05-4-59 = PSN J01263469+3137036 T. Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 18.0) on an unfiltered CCD image taken on July 31.071 UT with a 0.35-m reflector. The new object is located at R.A. = 1h26m34s.69, Decl. = +31o37'03".6 (equinox 2000.0, presumed), which is approximately 14".2 east and 5".1 north of the center of MCG +05-4-59 = PGC 5364. The variable was designated PSN J01263469+3137036 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011ix based on the spectroscopic confirmation reported below. Additional magnitudes for 2011ix (from unfiltered CCD images unless noted otherwise): 1991 Oct. 5, [20.5 (Digitized Sky Survey, red plate; via Boles); 1992 Sept. 30, [21.0 (Digitized Sky Survey, blue plate; via Boles); 2010 Oct. 17, [19.5 (Boles); Dec. 25, [19.5 (Boles); 2011 Aug. 1.481, V = 17.9 (Boles; 0.61-m Cassegrain reflector located at the Sierra Stars Observatory in Alpine County, California; limiting mag 20.5; position end figures 34s.71, 03".7); 2.394, 18.4 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera at the New Mexico Skies Observatory, Mayhill, NM, U.S.A.; position end figures 34s.70, 02".9; image posted at the following website URL: http://tinyurl.com/85cq32o); 3.461, 18.5 (Brimacombe); 4.446, 18.5 (Brimacombe); 5.465, 18.5 (Brimacombe); 7.470, 18.5 (Brimacombe; image posted at website URL http://www.flickr.com/photos/43846774@N02/6027195265/); 8.465, 18.6 (Brimacombe); 10.395, 18.6 (Brimacombe); 10.917, 18.5 (V.

Boles forwards a report by Avishay Gal-Yam et al. (posted at website URL http://www.astronomerstelegram.org/?read=3633) that their spectroscopy with the Palomar Observatory 5-m Hale telescope (+ DBSP spectrograph) on Aug. 28 shows good fits (via the Superfit supernova spectral-identification code of Howell et al. 2005, Ap.J. 634, 1190) for 2011ix to type-II supernovae (e.g., SN 1993W) several months after explosion.
