M. Papenkova and W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search (cf. IAUC 6627, 7126), report their discovery of an apparent supernova on an unfiltered image taken on May 16.2 UT (mag about 18.3) with the 0.8-m Katzman Automatic Imaging Telescope (KAIT), the object being confirmed on an earlier image taken on May 10.2 (mag about 18.8). SN 1999ce is located at R.A. = 11h28m51s.57, Decl. = +57o08'04".0 (equinox 2000.0), which is about 1".5 southeast of the nucleus of the host galaxy. KAIT images of the same field taken on May 1.3 (limiting mag about 19.0), Apr. 26.4 (limiting mag about 19.0) and Jan. 11.5 (limiting mag about 19.3) show nothing at the position of the new star.
