SN2002cc – discovery

Tom Boles

SN2002cc in anonymous galaxy, discovered 2002 April 8. IAU Circular 7871 : 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. SN2002cc is located at RA 8h 34m 01s.97, Dec +55º 39' 2".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 UK 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).
