The new object, which is also present at mag approximately 17.0 in an image taken on June 4.08, is located at R.A. = 19:15:51.46 ± 0".1, Decl. = -56:12:30.9 ± 0".1 (equinox 2000.0), which is about 1".7 west and 1".9 north of the center of the galaxy IC 4840. Nothing is visible at this position on archival images taken on May 1.24 (limiting mag 18.5) and Apr. 22.29 (limiting mag 18.0).
