SUPERNOVA 1999da IN NGC 6411

R. Johnson and W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search (cf. IAUC 6627, 7126), report the discovery of an apparent supernova with the 0.8-m Katzman Automatic Imaging Telescope (KAIT). SN 1999da was discovered on unfiltered images taken on July 5.4 UT (mag about 17.0) and confirmed on images taken on July 2.4 (mag about 17.6). The new object is located at R.A. = 17h35m22s.96, Decl. = +60o48'49".3 (equinox 2000.0), which is 71".3 west and 1".2 north of the nucleus of NGC 6411. A KAIT image of the same field on June 29.4 (limiting mag about 19.5) showed nothing at the position of SN 1999da.
