L. A. G. Monard, Pretoria, South Africa, reports his discovery of an apparent supernova (mag about 17.3 ± 0.2) on unfiltered ST-7 CCD images taken on Feb. 10.775 (and confirmed on Feb. 12.758 at mag about 17.4 ± 0.2) with a 0.30-m Schmidt-Cassegrain reflector. SN 2005ah is located at R.A. = 6h00m45s.77, Decl. = -58o35'20".8 (equinox 2000.0), which is 27" west and 8" north of the nucleus of a galaxy in the cluster Abell S560. Nothing is visible at this position on an image from the Digitized Sky Survey (limiting red mag 20.5) or on an image taken by Monard on Jan. 4.883 (limiting red mag 18.8).
