LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 15.2 ± 0.2) on an unfiltered image taken on Apr. 24.19 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object, which is also present at mag approximately 16.0 ± 0.3 in an image taken on Apr. 19.25, is located at R.A. = 10:08:49.94 ± 0".1, Decl. = -67:01:57.3 ± 0".1 (equinox 2000), which is about 1".6 west and 3".1 south of center of the galaxy IC 2554. Nothing is visible at this position on archival template-subtracted images taken on Apr. 11.23 (limiting mag 18.5) and Apr. 7.08 (limiting mag 19.0).
