The object, designated SN 2010iv, is located at R.A. = 4:03:52.23 ± 0".2, Decl. = -43:25:38.5 ± 0".2 (equinox 2000.0); it is right on the top of the small galaxy and completely dominating the visible light. Nothing is visible at this position on a stack of seventeen 40-s archival images taken between 2009 Nov. 5.13 and 2010 Aug. 13.28 (limiting mag 19.5).
