L. A. G. Monard, Calitzdorp, Western Cape, South Africa, reports his discovery of an apparent supernova (mag 16.3) on unfiltered CCD images taken on Aug. 12.771 and 13.713 UT. The new object is located at R.A. = 14:24:29.11, Decl. = -16:45:39.2 (equinox 2000.0; UCAC2 reference stars), which is 24" east and 8" north of the core of the Scd-type galaxy NGC 5597. Nothing is visible at this position in red Digitized Sky Survey images (limiting mag 20.5) or on earlier images taken by Monard to limiting mag 18.5 and deeper. The variable was designated PSN J14242911-1645392 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012es based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012es: 2012 May 10.93, [18.0 (Monard); Aug. 16.401, 16.2 (Joseph Brimacombe, Cairns, Australia; infrared filter, bandpass > 700 nm; position end figures 29s.13, 39".3; image posted at website URL http://www.flickr.com/photos/43846774@N02/7799238916/).
