SUPERNOVA 2002cc IN ANONYMOUS GALAXY

W. D. Li, University of California at Berkeley, reports the LOTOSS (cf. IAUC 7514) discovery of an apparent supernova (mag about 18.5) on unfiltered CCD images taken with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) on Apr. 4.2 and 9.3 UT. SN 2002cc is located at R.A. = 8h34m01s.97, Decl. = +55d39'12".4 (equinox 2000.0), which is 1".2 west and 5".3 north of the nucleus of an anonymous galaxy located about 65" west and 73" north of UGC 4470. A KAIT image of the same field on Mar. 25.3 UT showed nothing at this position (limiting mag about 19.5).

T. Boles, Coddenham, Suffolk, reports his independent discovery of this supernova at mag 17.2 on a 30-s unfiltered CCD image taken on Apr. 8.876 UT (limiting mag 18.5) with a 0.35-m Schmidt-Cassegrain reflector, in the course of the U.K. Nova/Supernova patrol. He provides end figures 02s.11, 12".5 and notes that the object is not present on his images from 2001 Dec. 10 (limiting mag 19.0), 2002 Jan. 17 or Feb. 16. It is also not present on Palomar Sky Survey images taken on 1997.908 (red, limiting mag 21.0) and 1991.110 (blue, limiting mag 20.5).
