P. Luckas, Perth, W. Australia; O. Trondal, Oslo, Norway; and M. Schwartz, Patagonia, AZ, report the discovery of an apparent supernova (mag 17.4) on unfiltered CCD frames taken with the 0.35-m telescope at Perth on May 20.54 UT and the 0.81-m telescope at Patagonia on May 22.17 in the course of the Tenagra Observatory Supernova Search. SN 2006ck is located at R.A. = 13h09m40s.42, = Decl. = -01o02'57".2 (equinox 2000.0), which is 10".2 west and 3".0 south of the center of UGC 8238 (which itself has position end figures 41s.10, 54".2). Nothing was visible at the position of 2006ck on an image taken by Luckas on Mar. 29.70 (limiting magnitude about 18.0) or on a Digitized Sky Survey image from 1989 Feb. 11 (limiting red mag 21.0).
