E. Briggs, J. Newton, and T. Puckett report the discovery of an apparent supernova (mag 17.6) on unfiltered CCD images (limiting mag 19.0) taken with a 0.35-m reflector at Portal, AZ, U.S.A., on June 5.189 UT in the course of the Puckett Observatory Supernova Search. The new object, is located at R.A. = 10:57:16.46, Decl. = +28:32:21.7 (equinox 2000.0), which is 3".6 west and 8".9 south of the center of PGC 32926. Puckett has posted an image of the variable at website URL http://www.possdata.com/PSNJ10571646+2832217.jpg. The variable was designated PSN J10571646+2832217 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012dd based on the spectroscopic confirmation reported below.
