The new object, which is also present in an image taken on June 7.27 at mag approximately 16.1 ± 0.2, is located at R.A. = 20:32:18.50 ± 0".1, Decl. = -19:43:59.6 ± 0".1 (equinox 2000), which is about 4".8 west and 0".6 south of the center of the galaxy ESO 597-6. Nothing is visible at this position on archival images taken on May 21.25 and June 2.19 (limiting mag 18.5).
