SUPERNOVA 2001J IN UGC 4729

S. Beckmann and W. D. Li, University of California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report the discovery of an apparent supernova (mag about 17.5) on unfiltered images taken on Jan. 15.4 and 16.3 UT with the 0.8-m Katzman Automatic Imaging Telescope (KAIT). SN 2001J is located at R.A. = 9h00m43s.23, Decl. = +17o37'15".6 (equinox 2000.0), which is 19".2 east and 2".4 south of the nucleus of UGC 4729. A KAIT image of the same field taken on 2000 Dec. 27.4 showed nothing at this position (limiting mag about 19.0).
