2012CBET.3233....1D

Colin Drescher, Calamvale, Queensland, Australia, reports the discovery of an apparent supernova (red mag 18.5) by Stuart Parker (Oxford, Canterbury, New Zealand) on a 30-s unfiltered image taken on Sept. 12.535 UT with a 35-cm Celestron C14 f/6.3 reflector (+ ST10 CCD camera) in the course of the "Backyard Observatory Supernova Search" (BOSS) program. The new object is located at R.A. = 2:45:28.36, Decl. = -62:07:21.0 (equinox 2000.0; measured by Drescher), which is 10" west and 9" north of the nucleus of the galaxy PGC 127935 = IRAS 02443-6220. Parker subsequently found the variable to be present on earlier images that he took on July 17.672 (at red mag 17.7 and position end figures 28s.41, 21".4, as measured by Drescher), July 27, and Aug. 29. Nothing is visible at this position on an image by Parker taken on Apr. 24.293, to limiting red mag 18.4. The variable was designated PSN J02452841-6207214 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012ew based on the spectroscopic confirmation reported below.
