Greg Bock, Windaroo, Queensland, Australia, reports the discovery of an apparent supernova (mag 17.3) by Stuart Parker (Oxford, Canterbury, New Zealand) on a 35-s unfiltered CCD image taken on Sept. 22.34 with a 30-cm Astro-Tech AT12RC Ritchey-Chretien astrograph (+ ST10 camera), as part of a collaboration by the Backyard Observatory Supernova Search (BOSS). The new object is located at R.A. = 20:31:33.45, Decl. = -44:09:17.3 (equinox 2000.0; measured by Bock), which is within an arc second southeast of the center of the nucleus of the presumed host galaxy. Parker obtained a confirming image on Sept. 23.48 with a 35-cm Celestron reflector, adding that nothing was visible at the position of the new object on an image that he took on Sept. 12 (no limiting magnitude provided). Nothing is visible on red and infrared Digitized Sky Survey images (limiting red mag > 19). The variable was designated PSN J20313345-4409173 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012ft based on the spectroscopic confirmation reported below. Joseph Brimacombe, Cairns, Australia, writes that he obtained six 15-min images with an infrared filter (wavelength > 700 nm) on Sept. 24.408, yielding mag 17.4 and position end figures 33s.56, 17".2; he posted his image at the following website URL: http://www.flickr.com/photos/43846774@N02/8042721429/.
