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) on an unfiltered image taken on Oct. 18.04 UT with the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo. The new object, which is also present at mag approximately 16.7 in an image taken on Oct. 19.00, is located at R.A. = 18:36:36.91 ± 0".2, Decl. = -47:03:15.7 ± 0".2 (equinox 2000.0), which is about 3".1 west and 0".5 south of center of the galaxy ESO 281-14. Nothing is visible at this position on archival images taken on Sept. 22.09 (limiting mag 18.0) and Sept. 9.14 (limiting mag 18.5).
