SUPERNOVA 2001dm IN NGC 749

B. A. Beutler, M. Modjaz and W. D. Li, University of California at Berkeley, report the discovery by LOTOSS (cf. IAUC 7514) of an apparent supernova (mag about 15.4) in unfiltered images taken with the Katzman Automatic Imaging Telescope on Aug. 7.5 and 8.5 UT. The new object is at R.A. = 1h55m40s.55, Decl. = -29d55'20".7 (equinox 2000.0), which is 6".9 west and 0".4 north of the nucleus of NGC 749. A KAIT image of the field taken on 2000 Dec. 28.2 showed nothing at this position (limiting mag about 18.0).
