SUPERNOVA 2002ef IN NGC 7761

B. Beutler and W. D. Li, University of California at Berkeley, report the LOTOSS (cf. IAUC 7906) discovery of an apparent supernova on unfiltered KAIT CCD images taken on July 30.4 (mag about 16.5) and 31.4 UT (mag about 16.2). SN 2002ef is located at R.A. = 23h51m29s.54, Decl. = -13o22'46".4 (equinox 2000.0), which is 10".0 east and 7".0 north of the nucleus of NGC 7761. A KAIT image of the same field on July 16.4 UT showed nothing at this position (limiting mag about 18.0).
