Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report a discovery of possible nova (mag.= 10.3) in Cep on two 40-s unfiltered CCD frames taken around 2013 Feb. 02.4119 UT ( limiting magnitude=13.5 ), using a 105-mm f/4 camera lens (+SBIG STL6303E camera). We have confirmed immediately the appearance of our discovery this PN on five 3-s unfiltered CCD frames taken around 2013 Feb 02.4327 UT ( limiting magnitude=17.5 ), using a Meade 200R 0.40-m f/9.8 reflector (+SBIG STL1001E camera). (lens magnitude of referred catalogue Hipparcos, others reference catalogue GSC-ACT) Nothing is visible at this location on two past survey frames taken on 2013 Jan 23.411 UT(limiting mag.= 13.6) and 26.401 UT (limiting mag.= 13.6) nor on 2MASS,USNO-B1.0, but prediscover mag=11.9 Jan. 28.412 UT ( limiting magnitude = 13.7 ),. mag=11.0 Jan. 30.413 UT ( limiting magnitude = 13.5 ),. We have checked in Minor Planets. nearest star in USNO B1.0 has position end figures 04s17, 59"9, distance 8".7, magnitudes B2=17.23 R2=15.98 I=14.65
