SUPERNOVA 2000cc IN CGCG 140-014

Y. Sato and W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search (cf. IAUC 6627, 7126), report the discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) of an apparent supernova on unfiltered images taken on Apr. 30.5 (limiting mag about 19.0) and May 1.5 UT (limiting mag about 20.5), both showing the new star at mag about 18.5. SN 2000cc was also present on an unfiltered image taken on Apr. 26.5 at about the same brightness, and the new object is located at R.A. = 17h23m14s.34, Decl. = +23o40'18".7 (equinox 2000.0), which is 5".9 east and 9".1 south of the nucleus of CGCG 140-014. Unfiltered images of the field taken on 2000 Apr. 10.5 (limiting mag about 19.0) and 1998 July 16.3 (limiting mag about 19.5) showed nothing at the position of the new object.
