R. Martin, Perth Observatory, reports the discovery of an apparent supernova (mag 16.0) on CCD images taken on Mar. 15.83 and 16.67 UT in the course of the Perth Automated Supernova Search. The new object is located at R.A. = 19h09m53s.62, Decl. = -63o49'24".1 (equinox 2000.0), which Martin reports as being 123" east and 118" north of the center of NGC 6744. Nothing was visible at this location in an image taken on 2004 Aug. 8.75. H. Yamaoka, Kyushu University, suggests that the offset should perhaps be 49" east, given the positions of the galaxy center with respect to the above-reported position, adding that there is a foreground star (mag about 18) located about 5" south of Martin's position. L. A. G. Monard, Pretoria, S. Africa, reports his independent discovery of SN 2005at on CCD images taken on Mar. 5.139 (at mag 14.3) and 19.133 (mag 14.4), providing position end figures 53s.57, 22".8 (or 46" east and 117" north of the center of NGC 6744). Monard adds that nothing is visible at this location on his image from 2004 Feb. 15.1 (limiting red mag 17.3) or on an image fromthe Digitized Sky Survey (limiting red mag 20).
