SUPERNOVA 1999ge in NGC 309

Y. Sato and 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 309. The SN was discovered and confirmed on unfiltered images taken on Nov 27.2 UT (mag about 17.2) and Nov 28.2 UT (mag about 16.9) respectively. The new object is located at R.A.=0h56m43s.76, Decl.= -9 54'43".0 (equinox 2000.0), which is 16".0 east and 6".7 north of the nucleus of NGC 309. A KAIT image of the same field on Oct 31.3 UT (limiting magnitude about 19.0) showed nothing at the position of the SN.
