S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki (Teppo-cho, Yamagata) of an apparent supernova (mag 17.0) on unfiltered CCD frames (limiting magnitude 19.0) taken on May 15.61 UT using a 0.60-m f/5.7 reflector (+ Bitran BT-214E camera). The new object, which was also found at mag 16.3 by Itagaki on an unfiltered pre-discovery frame taken on May 1.65 with a 0.50-m f/6 reflector, is located at R.A. = 13:29:25.03 ± 0s.01, Decl. = +11:47:46.4 (equinox 2000.0), which is 11" east and 3" south of the center of NGC 5177. Nothing is visible at this position on Itagaki's many past frames (including on 2007 Mar. 17.66, limiting mag 19.0) or on the Digitized Sky Survey; his pre-discovery and discovery images are posted at website URL http://www.k-itagaki.jp/images/psn5177.jpg.
