Graham and W. Li report the LOSS discovery of an apparent supernova on an unfiltered KAIT image taken on Aug. 1.19 UT (mag about 17.6). The new object was confirmed on earlier images taken on July 30.19 (mag about 18.6), and 31.20 (mag about 18.0). SN 2004dk is located at R.A. = 16h21m48s.93, Decl. = -2o16'17".3 (equinox 2000.0), which is 4".4 east and 43".5 north of the nucleus of NGC 6118. KAIT images on July 29.21, 27.19 and 25.20 showed nothing at this position to limiting mags 18.0, 18.5 and 19.5, respectively.
