2010CBET.2345....1P

M. Peoples, J. Newton, and T. Puckett report the discovery of an apparent supernova (mag 16.6) on unfiltered CCD images (limiting mag 18.5) taken with a 0.40-m reflector at Portal, AZ, U.S.A., on June 28.39 UT in the course of the Puckett Observatory Supernova Search. The new object, which was confirmed at mag 16.6 on images (limiting mag 19.8) taken by P. Mortfield and S. Cancelli on June 29.48 with a 0.40-m reflector at Sierra Remote Observatories in California, is located at R.A. = 18:37:11.88, Decl. = +30:37:49.6 (equinox 2000.0), which is 4".6 west and 7".1 north of the center of the presumed host galaxy. Nothing is visible at this position on images taken by Puckett on June 13 (limiting mag 19.1); however, T. Orff reports a precovery image (limiting magnitude of 18.5) taken by Puckett on June 20, which shows 2010ew at mag 17.1.
