C. Drescher, Calamvale, Queensland, Australia, reports the discovery of an apparent supernova (red mag 17.0) by Stuart Parker (Oxford, Canterbury, New Zealand) on a 40-s unfiltered CCD image taken on Oct. 18.566 UT with a 35-cm f/6.3 Celestron C14 Schmidt-Cassegrain reflector (+ ST8 CCD camera), the new object being located at R.A. = 5:40:05.30, Decl. = -55:32:03.9 (equinox 2000.0), which is 37" west and 19" north of the nucleus of the galaxy PGC 17571 = ESO 159-23 (measured by Drescher, using Astrometrica with the USNO-B1.0 catalogue). Nothing was visible at this position on an image taken by Parker on Sept. 19.596 (limiting red mag 19.0). Drescher adds that the new star is clearly visible in multiple 35-s unfiltered CCD confirmation images taken around Oct. 19.534 by P. Marples (Loganholme, Queensland, Australia; 30-cm f/7 LX200ACF reflector + Starlight Xpress SXVH9 CCD camera), from which Drescher measured position end figures 05s.27, 04".1 and red mag 17.1. Nothing is visible at the position of 2009jz on a Digitized Sky Survey image from 1991 Feb. 14 (limiting red magnitude 20.0) or on an image taken by Marples on 2009 Jan. 15.485 (limiting red magnitude 17.6).
