Discoverd by K. Itagaki, Yamagata, Japan, on an unfiltered CCD frame using 0.50-m f/6 reflector at Yamagata under the limiting magnitude= 19.0, who writes nothing is visible at this location on his past frames, but unfortunately he has no recent frame and the discovery image is at http://www.k-itagaki.jp/images/psn-p.jpg.

I took a confirmation image of this PSN with 0.50-m f/4.5 CDK astrograph + FLI-PL11002M CCD camera of iTelescope.NET at Mayhill, NM, USA, remotely. Photometric result was V=16.83. Position end figures were 16.68 and 25.52 in R.A. and Dec.. My image available at http://meineko.sakura.ne.jp/ccd/PSN_J10491665-1938253.jpg (Seiichiro Kiyota, Kamagaya, Japan)

Mag.=17.2 U, position end figures 16s.66, 24".9, on an image composed from 3-frames which were taken by each 180-seconds exposure under the limiting magnitude = 19.5, remotely using a 0.50-m f/6.8 astrograph + CCD(FLI ProLine PL11002M) + f/4.5 focal reducer at the iTelescopeNET Mayhill, New Mexico, USA. Offset of the supernova from the galaxy center is 1" W, 12" S. Observer T. Yusa, Osaki, Japan. See an image at http://space.geocities.jp/yusastar77/supernova/PSNinP032373_yus.htm
