In follow-up observation, this possible supernova was detected with images (exp. time was 3 min, each) using 0.50-m f/6.8 astrograph + FLI ProLine PL11002M CCD + f/4.5 focal reducer (T11, iTelescope.NET, Mayhill, USA). Photometry results were V=15.87 and Rc=15.63. Seiichiro Kiyota (Tsukuba, Japan). My image is available at http://meineko.sakura.ne.jp/ccd/PSN_J22370217+3424052-130422.jpg

Mag.= 15.8, position end figures 02s.23, 04".7 observed by T. Noguchi, Chiba-ken, Japan, from a stocked frame (limiting mag.= 18.0) exposed by 30-s x 8 using 0.23-m f/6.3 Schmidt-Cassegrain + unfiltered CCD. Position and magnitude were measured from UCAC3.

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J22370217+3424052 in NGC 7331. Object visible on 3x150sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.45-m f/2.8 telescope + CCD (KAF09000) on Apr. 23.4487, 2013. Object located at 22h 37m 02s.19 +/- 0".09, +34d 24' 04".8 +/- 0".08 (UCAC-4) with magnitude 15.5U (mag. limit ~19.3m). Nothing is visible at this position on the POSS and POSSII images.
