Ron Arbour (South Wonston, Hants, U.K.) reports the discovery of an apparent supernova (mag 16.5) on an unfiltered CCD image taken on Sept. 19.879 UT using a 35-cm f/6 Schmidt-Cassegrain telescope (+ SXVF H9 camera) in the course of his supernova patrol. The new object is located at R.A. = 16:15:44.86, Decl. = +31:57:47.7 (equinox 2000.0), which is 3" east and 2" south of the center of the galaxy NGC 6103. Nothing was visible at this position on digitized Palomar Sky Survey plates from 1989 May 3 (red) and 1994 Apr. 19 (blue). The variable was designated PSN J16154486+3157477 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012fj based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012fj: Sept. 20.850, 16.1 (D. Grennan, Dublin, Ireland; 0.35-m reflector; position end figures 44s.80, 48".4 with uncertainty 0".5 in each coordinate; precise astrometry and photometry difficult due to the proximity of the new object to the core of NGC 6103; image posted at URL http://www.webtreatz.com/images/J16154486+3157477.jpg); Sept. 21.138, 16.9 (J.
