Haislip, A. Crain, D. Foster, M. Nysewander, and A. LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 16.2) on an unfiltered image taken on Nov. 12.09 UT with the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo. The new object, which is also present at mag approximately 15.0 in an image taken at Cerro Tololo with the CHASE 50-cm telescope on Nov. 13.11, is located at R.A. = 5h19m34s.47 +/- 0".2, Decl. = -32°39'14".6 +/- 0".2 (equinox 2000.0), which is about 16".8 west and 13".6 north of the center of the galaxy ESO 362-18. Nothing is visible at this position on archival images taken with the "PROMPT 5" telescope on Nov. 6.27 (limiting mag 17.5) and Oct. 23.22 (limiting mag 18.0).
