H. Yamaoka, Kyushu University, forwards the discovery by K. Itagaki (Yamagata, Japan) of a possible nova on May 24.672 UT during a survey program performed by himself and H. Kaneda (Hokkaido, Japan). The variable, which was designated PNV J21095047+1348396 when posted on the Central Bureau's TOCP webpage, was confirmed at unfiltered CCD mag about 11.5 by Itagaki with a 0.60-m reflector on May 24.699, the position measured to be R.A. = 21:09:50.47, Decl. = +13:48:39.6 (equinox 2000.0); Itagaki has posted his confirmation image at website URL http://www.k-itagaki.jp/images/pnv.jpg. Additional approximate magnitudes for PNV J21095047+1348396 (unfiltered CCD unless noted otherwise): May 17.71, [14.9 (Itagaki, 0.21-m reflector); May 18.76, [12.3 (Itagaki, 180-mm-f.l. telephoto lens); May 25.3, 11.0 (Ernesto Guido and Giovanni Sostero; remotely with a 0.25-m f/3.4 reflector at the GRAS Observatory near Mayhill, NM, U.S.A.; position end figures 50s.46, 39".6, which they also note to be very close to a star of red mag 18.8 in the USNO- B1.0 catalogue; their image compared to a red Digitized Sky Survey plate from 1991 is posted at website URL http://bit.ly/mycwOt); May 25.676, 11.6 (K. Kadota, Ageo, Japan; 0.25-m f/5 reflector + SBIG ST-9E camera; position end figures 50s.47, 39".7; communicated by S. Nakano, Sumoto, Japan; image posted at URL http://members.jcom.home.ne.jp/kenic-k/image/PNVinPeg-20110525.jpg); May 26.076, 11.5 (P. Schmeer, Bischmisheim, Germany; visual). Itagaki/Yamaoka note also that a faint star (mag about 19) is located within several arcsec of Itagaki's position in the USNO-B1.0 catalogue (position end figures 50s.427, 39".95).
