C. Drescher, Calamvale, Queensland, Australia, reports the discovery of an apparent supernova (red mag 15.4) by Stuart Parker (Oxford, Canterbury, New Zealand), on an unfiltered CCD image taken by Parker on Apr. 19.755 UT with a 35-cm Celestron C14 f/6.3 Schmidt-Cassegrain telescope (+ ST10 camera). Drescher measures the position of 2010bv to be R.A. = 22:14:01.89, Decl. = -26:55:44.6 (equinox 2000.0; using Astrometrica software with the USNO-B1.0 catalogue), which is 15" west and 31" north of the nucleus of the galaxy PGC 68345 (= ESO 533-4). The object is also visible on images taken by Parker on April 20.668, from which Drescher measured position end figures 1s.91 and 44".4. Confirmation images taken by J. Brimacombe (Cairns, Queensland, Australia) taken on Apr. 20.779 with a 40-cm Ritchey-Chretien telescope (+ U16 camera) also show 2010bv (no position or magnitude provided). Nothing is visible at the position of 2010bv on a Digitized Sky Survey image from 1995 Aug. 29 (limiting red magnitude 20.5).
