Wozniak, Los Alamos National Laboratory, report the discovery of an apparent supernova (V magnitude about 17.0) on images obtained in the course of the "All Sky Automated Survey for SuperNovae (ASAS-SN)" with the double 14-cm "Cassius" telescope at Cerro Tololo on June 14.25 UT. The new object is located at R.A. = 22h02m15s.45, Decl. = -61d39'34".6 (equinox 2000.0), which is approximately 0".41 ast and 0".04 south of the center of the galaxy APMUKS(BJ) B215839.70-615403.9. Additional magnitudes for the variable: May 15.33, [17.3; 18.32, 17.3 (marginal detection); 22.32, 17.2; 26.31, 17.0; 27.34, 16.9; June 8.36, 16.9; 9.25, 16.8; 11.40, 17.1; 12.22, 17.1; 13.23, 16.9.
