J. Newton and T. Puckett report the discovery of an apparent supernova (mag 17.5) on unfiltered CCD images (limiting mag 19.4) taken with a 0.40-m reflector at Portal, AZ, U.S.A., on Mar. 29.125 UT in the course of the Puckett Observatory Supernova Search. The new object (which was designated PSN J07451362+5304107 when posted on the Central Bureau's TOCP webpage and is here designated SN 2011bh based on the spectroscopic report below) is located at R.A. = 7:45:13.62, Decl. = +53:04:10.7 (equinox 2000.0), which is 1".4 east and 20".2 south of the center of NGC 2431. Additional unfiltered CCD magnitudes for 2011bh: Mar. 17, [19.0 (Puckett); 30.101, 17.4 (Puckett); 30.190, 17.1 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera at New Mexico Skies Observatory, Mayhill, NM, U.S.A.; position end figures 13s.59, 09".2); 31.532, 17.5: (Kuniaki Goto, Japan, 35-cm Schmidt-Cassegrain telescope + SBIG ST-8XME camera; possible independent discovery; communicated by J. Watanabe, National Astronomical Observatory of Japan; only approximate position given). Brimacombe's image is posted at website URL http://www.flickr.com/photos/43846774@N02/5573455901/.
