W. Li, University of California at Berkeley, reports the discovery of an apparent supernova by the Lick Observatory Supernova Search (LOSS; cf. IAUC 6627, 7126) with the 0.8-m Katzman Automatic Imaging Telescope (KAIT). SN 1999bg was found and confirmed on unfiltered CCD frames taken on Mar. 28.3 and 29.3 UT (mag about 15.5 on both dates). The new object is located at R.A. = 12h04m07s.30, Decl. = +62o30'01".2 (equinox 2000.0), which is about 33" west and 20" south of the nucleus of IC 758. A KAIT image of the same field on Feb. 28.4 (limiting mag about 18.0) showed nothing at the position of SN 1999bg.
