Blanchard, S. B. Cenko, W. Li, and A. V. Filippenko report the LOSS discovery of an apparent supernova on unfiltered KAIT images: SN 2011 UT R.A. (2000.0) Decl. Mag. Offset 2011bq Apr. 15.52 18 29 22.36 +39 42 34.5 17.9 1".0 W, 14".0 S This variable was designated PSN J18292236+3942345 when posted on the Central Bureau's TOCP webpage and is here designated SN 2011bq based on the spectroscopic report below. Additional CCD magnitudes for 2011bq: 2010 Oct. 15.14 UT, [19.1 (KAIT); 2011 Apr. 16.391, 17.8 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera + red filter at New Mexico Skies Observatory, Mayhill, NM, U.S.A.; position end figures 22s.44, 34".8). Brimacombe's image is posted at the following website URL: http://www.flickr.com/photos/43846774@N02/5624024607/. J. M. Silverman and A. V. Filippenko, University of California, Berkeley, report that inspection of a CCD spectrum (range 340-1000 nm), obtained by A. Sonnenfeld and D. Sand (University of California, Santa Barbara) on Apr. 16 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that PSN J18292236+3942345 = SN 2011bq is a type-II supernova with well-developed Balmer lines having P-Cyg profiles; after removal of the host-galaxy recession velocity of 5800 km/s, determined from narrow emission features, the absorption minimum of the H-alpha line is found to be blueshifted by about 6300 km/s. Cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2011bq is a type-IIP supernova at 2 to 3 months past maximum brightness.
