LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent Supernova (mag approximately 17.4 +/- 0.2) on an unfiltered image taken on Nov. 15.10 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object is also present in an image taken on Nov. 17.04 at mag approximately 17.0 +/- 0.2. SN 2008hg is located at R.A. = 1h40m22s.39 +/- 0".1, Decl. = -28o55'05".1 +/- 0".1 (equinox 2000), which is about 12".0 east and 15".9 south of center of the galaxy IC 1720. Nothing is visible at this position on archival images taken on Oct. 31.15 and Nov. 4.09 (limiting mag 18.0).
