Puckett, Ellijay, GA, U.S.A.; and R. Gagliano, Cottonwood, AZ, U.S.A., report the discovery of an apparent supernova (mag 17.2) on unfiltered CCD images (limiting mag 19.3) taken with a 0.60-m reflector at Ellijay on June 6.27 UT in the course of the Puckett Observatory Supernova Search. The new object was confirmed at mag 17.2 on images (limiting mag 18.3) taken by T. Orff and S. Walters on June 8.10 with a 0.40-m reflector in Effort, PA, U.S.A. SN 2008cy is located at R.A. = 15h16m52s.10, Decl. = -13o25'14".0 (equinox 2000.0), which is 9".2 west and 6".4 south of the center of MCG -02-39-16. Nothing is visible at this position on images taken by Puckett on May 26 (limiting mag 18.8). G. Pignata, J. Maza, M. Hamuy, R. Antezana, L. Gonzalez, P. Gonzalez, P. Lopez, S. Silva, and G. Folatelli, Universidad de Chile; and D. Reichart, K. Ivarsen, A. Crain, D. Foster, M. Nysewander, and A. LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report their independent discovery of 2008cy on Luminance-filter images taken on June 7.09 (at mag approximately 16.0) and 7.99 UT (mag approximately 15.9) with the 0.41-m "PROMPT 2" telescope at Cerro Tololo. They measure the position of 2008cy to be R.A. = 15h16m52s.09 +/- 0".2, Decl. = -13o25'14".0 +/- 0".2 (equinox 2000), which is about 8".9 west and 7".0 south of center of the apparent host galaxy. Nothing is visible at this position on archival images taken on May 25.08 and 20.13 (limiting mag 18.0).
