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 15.3 +/- 0.2) on unfiltered images taken on May 12.07 and 13.03 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object is located at R.A. = 13h14m20s.47 +/- 0".1, Decl. = -46o06'44".9 +/- 0".1 (equinox 2000.0), which is situated between the pair of interacting galaxies that share the designation ESO 269-74. Nothing is visible at this position on archival images taken on Apr. 22.14 (limiting mag 19.0) and 28.13 (limiting mag 18.5).
