Greg Bock, Windaroo, Queensland, Australia, reports the discovery of an apparent supernova (red mag 16.3) by Stuart Parker (Oxford, Canterbury, New Zealand) on a 30-s unfiltered CCD exposure taken on July 8.52 UT with a 28-cm Celestron C11 reflector (+ ST10 camera). The new object is located at R.A. = 20:23:36.26, Decl. = -28:16:43.4 (equinox 2000.0; measured by Bock using the USNO-B and UCAC3 catalogues for reference stars), which is 35" west and 3" south of the nucleus of the galaxy ESO 462-16 = PGC 64605. Nothing is visible at this position on red and infrared images from the Digitized Sky Survey (limiting red magnitude > 19) or on an unfiltered 30-s image of ESO 462-16 taken by Stuart on 2011 Apr. 1 (limiting red magnitude > 18.0).
