2011CBET.2868....1B

Greg Bock, Windaroo, Queensland, Australia, reports the discovery of a possible supernova (red mag 14.5, measured by Colin Drescher, Calamvale, Queensland) on a 30-s unfiltered CCD image taken with a Meade LX200R 35-cm telescope (+ ST10XE camera) on Oct. 19.408 UT. The new object is located at R.A. = 19:54:21.42, Decl. = -58:42:39.0 (equinox 2000.0; measured by Drescher), which is 16" west and 10" north of the nucleus of the galaxy IC 4901. Nothing is visible at this position on an image taken on Sept. 20.52 by Bock (limiting red mag > 17.1) or on a red Digitized Sky Survey image (no date or limiting magnitude specified). The variable was designated PSN J19542142-5842390 when it was posted on the Central Bureau's TOCP webpage and is here designated SN 2011gv based on the spectroscopic confirmation reported below.
