Marchi, Universidad de Chile; B. Conuel, Wesleyan University; 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 the discovery of an apparent supernova (mag approximately 14.9 +/- 0.1) on a "Luminance"-filtered image taken on Jan. 14.07 UT with the 0.41-m 'PROMPT 2' telescope located at Cerro Tololo. The new object, which was confirmed in a similar image taken on Jan. 15.06 at mag approximately 15.0 +/- 0.1, is located at R.A. = 4h36m36s.77 +/- 0".1, Decl. = -0°08'35".6 +/- 0".1 (equinox 2000), which is about 8".7 west and 1".5 north of the center of the galaxy NGC 1620. Nothing is visible at this position on archival images taken on 2008 Dec. 18.14 and 2009 Jan. 11.08 (limiting mag 18.0).
