SUPERNOVA 1999dp IN UGC 3046

W. D. Li, University of California at Berkeley, on behalf of the Lick Observatory Supernova Search (LOSS; cf. IAUC 6627, 7126), reports the discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT), of an apparent supernova in UGC 3046. SN 1999dp was discovered on an unfiltered image taken on Sept. 2.5 UT and was confirmed on earlier images taken on Aug. 18.5, 25.5, and 28.5, all showing the star at mag about 18.2. The new object is located at R.A. = 4h29m16s.66, Decl. = +69o32'00".6 (equinox 2000.0), which is 18".0 west and 7".8 north of the nucleus of UGC 3046. There is a nearby star (mag about 16.5) with position end figures 15s.87, 02".4. A KAIT image of the same field on 1998 Aug. 31.5 (limiting magnitude about 19.5) showed nothing at the position of SN 1999dp.
