SUPERNOVA 1999gd in NGC 2623

W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search (cf. IAUC 6627, 7126) with the 0.8-m Katzman Automatic Imaging Telescope (KAIT), report the discovery of an apparent supernova in NGC 2623. The SN was discovered and confirmed on unfiltered images taken on Nov 24.5 UT (mag about 17.8) and Nov 25.6 UT (mag about 17.4) respectively. The new object is located at R.A.=8h38m24s.61, Decl.= +25o45'33".1 (equinox 2000.0), which is 7".3 east and 17".4 north of the nucleus of NGC 2623. KAIT images of the same field on Nov 22.5 UT (limiting magnitude about 18.0) and Nov 5.5 UT (limiting magnitude about 19.0) showed nothing at the position of the SN.
