S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki (Teppo-cho, Yamagata) of an apparent supernova (mag 16.4) on unfiltered CCD frames (limiting magnitude 19.0) taken on Aug. 9.705 UT using a 0.60-m f/5.7 reflector (+ Bitran BT-214E camera). The new object is located at R.A. = 17:58:22.56 ± 0s.02, Decl. = +50:47:34.0 ± 0".4 (equinox 2000.0), near a small and faint galaxy. Toru Yusa (Osaki, Japan) reports his confirming images (limiting mag 18-19) of the new object taken remotely at the RAS Observatory near Mayhill, NM, U.S.A., on Aug. 10.148 and 10.169, providing position end figures 22s.56 +/0 0s.01, 34".6 ± 0".1. Additional unfiltered CCD magnitudes for the variable, including pre-discovery images found by Itagaki from his archive: 2008 Aug. 31.50, [19.5 (Itagaki); 2010 Aug. 3.614, 17.5 (Itagaki); 6.576, 16.9 (Itagaki); 10.148, 16.0 (Yusa, 0.30-m f/12 reflector + FLI IMG1024-DM camera); 10.169, 16.0 (Yusa, 0.25-m f/3.4 reflector + SBIG ST-10XME camera); 10.446, 16.2 (Itagaki); 10.527, 16.3 (Yusa, 0.30-m f/12 Cassegrain reflector + SBIG STL-1001E camera at Osaki, Japan).
