2011CBET.2964....1B

Greg Bock, Windaroo, Queensland, Australia, reports the discovery by Stuart Parker (Oxford, Canterbury, New Zealand) of an apparent supernova (mag 18.0) on a 30-s unfiltered CCD image taken on Dec. 22.431 UT using a 35-cm F/6.3 Celestron C14 reflector (+ ST10 CCD camera). The new object is located at R.A. = 0:08:34.57, Decl. = -33:51:14.8 (equinox 2000.0; measured by Bock using the USNO-B and UCAC3 catalogues), which is 2" east and 16" north of the nucleus of the galaxy NGC 10. Nothing is visible at this position on Digitized Sky Survey red and infrared images (limiting red magnitude > 19) or on Parker's image taken on 2011 Nov. 30 (limiting red mag 18.6). The variable was designated PSN J00083457-3351148 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011jo based on the spectroscopic confirmation reported below.
