2012CBET.3190....1B

Greg Bock, Windaroo, Queensland, Australia, reports the discovery of an apparent supernova (mag 15.3) by Stuart Parker (Oxford, Canterbury, New Zealand) on unfiltered images taken on June 30.55 and July 1.48 UT using a 35-cm Celestron C14 reflector (+ ST10 CCD camera). The new object is located at R.A. = 21:49:16.32, Decl. = -60:42:42.6 (equinox 2000.0; measured by Bock using the USNO-B and UCAC3 catalogues), which is 2" east and 4" north of the nucleus of the galaxy NGC 7125. Nothing is visible at this position on Digitized Sky Survey red and infrared images (limiting red magnitude > 19. The variable was designated PSN J21491632-6042426 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012du based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012du: 2012 May 19, [18.0 (Parker); July 1.701, 15.8 (Joseph Brimacombe, Cairns, Australia; 43-cm CDK telescope + STL6K camera + infrared filter; bandpass > 700 nm; position end figures 16s.22, 43".2; image posted at website URL http://www.flickr.com/photos/43846774@N02/7484414708/); 3.636, 15.6 (Brimacombe; position end figures 16s.25, 43".6; image posted at URL http://www.flickr.com/photos/43846774@N02/7498206362/); 17.781, 15.6 (Brimacombe; position end figures 16s.25, 43".8; image posted at URL http://www.flickr.com/photos/43846774@N02/7595534698/).
