SUPERNOVA 1999bh IN NGC 3435

Li also reports the discovery by LOSS of another apparent supernova in an unfiltered image taken on Mar. 29.2 UT (mag about 16.8). SN 1999bh was confirmed at mag 17.5 on an earlier image taken on Mar. 24.2 and is located at R.A. = 10h54m46s.97, Decl. = +61o17'20".0 (equinox 2000.0), which is about 10" west and 3" south of the nucleus of NGC 3435. A KAIT image of the same field on Mar. 17.2 (limiting mag about 19.0) already showed a hint of SN 1999bh, and a KAIT image on Mar. 12.2 (limiting mag about 19.0) showed nothing at the position of the supernova.
