SUPERNOVA 2002de IN NGC 6104

M. Papenkova and W. D. Li, University of California at Berkeley, report the LOTOSS (cf. IAUC 7906) discovery of an apparent supernova (mag about 16.0) on unfiltered CCD images taken with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) on June 1.4 and 2.4 UT. SN 2002de is located at R.A. = 16h16m30s.38, Decl. = +35o42'30".2 (equinox 2000.0), which is 4".0 west and 1".0 north of the nucleus of NGC 6104. KAIT images taken on May 13.4 (limiting mag about 19.0) and 23.4 (limiting mag about 18.0) showed nothing at this position.
