Hamuy, R. Antezana, and L. Gonzalez, 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 the behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 15.2) on an unfiltered image taken on Nov. 5.32 UT with the 0.46-m "PROMPT 3" telescope located at Cerro Tololo. The new object, which is also present at mag approximately 15.4 in an image taken on Nov. 6.33, is located at R.A. = 6h05m10s.80 +/- 0".1, Decl. = -49o17'59".06 +/- 0".1 (equinox 2000), which is about 0".9 east and 0".1 south of the center of the galaxy ESO 205-G18. Nothing is visible at this location on archival images from Oct. 13.22 (limiting mag 18.5).
