LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 17.7 ± 0.4) on unfiltered images taken on Nov. 16.27 and 17.27 UT with the 0.41-m 'PROMPT 4' telescope located at Cerro Tololo. The new object is located at R.A. = 9:53:22.52 ± 0".1, Decl. = -18:38:26.1 ± 0".1 (equinox 2000.0), which is about 1".3 west and 3".6 north of the center of the apparent host galaxy, which itself is a small galaxy located to the east of NGC 3045. Nothing is visible at this position on archival images taken on Apr. 9.06 (limiting mag 19.0) and Nov. 4.32 (limiting mag 18.1).
