Ralph Martin, Perth Observatory, reports the discovery of an apparent supernova (mag 15.5) in red-filtered CCD images (limiting magnitude 18.5) taken on Mar. 26.780 UT and confirmed on Mar. 30.833 with the 0.6-m Perth/Lowell Automated Telescope. He initially reported the the new object to be located at R.A. = 19:15:34.4, Decl. = -54d37m40s (equinox 2000.0), which is 1".9 east and 3".6 south of the center of IC 4839; as a result, the variable was designated PSN J19153440-5437400 when it was posted on the Central Bureau's TOCP webpage and is here designated SN 2011ed based on the spectroscopic report below. Martin later remeasured the position of 2011ed as R.A. = 19:15:34.34, Decl. = -54:37:39.5. Additional unfiltered CCD magnitudes for 2011ed: Mar. 10.833, [18.5 (Martin); Apr. 3.150, 14.8 (L. A. G. Monard, Calitzdorp, Western Cape, South Africa; position end figures 34s.35, 39".6; offset 1".3 east, 1".2 south); 6.664, 15.0 (Joseph Brimacombe, Cairns, Australia; remotely using a 41-cm RCOS telescope + U9000 camera at Macedon Ranges Observatory, near Melbourne, Victoria; position end figures 34s.42, 39".2).
