Koichi Nishiyama, Kurume, Japan and Fujio Kabashima, Miyaki, Japan report a discovery of possible nova (mag.= 10.9) in Cyg on two 40-s unfiltered CCD frames taken around 2014 Mar. 31.78990 UT (limiting magnitude=13.1), using a 105-mm f/4 camera lens (+SBIG STL6303E camera). We have confirmed immediately the appearance of our discovery this PN on five 5-s unfiltered CCD frames taken around 2014 Mar. 31.8202 UT (limiting magnitude=17.6), 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 past survey frames taken on 2014 Mar. 27.781 UT (limiting mag.= 13.4) but we found same object 12.4 mag. Mar. 30.769 UT (limiting mag.= 13.5) nor on DSS, USNO-B1.0, We have checked in Minor Planets. nearest star in USNO B1.0 has position end figures 42s769, 33"99, distance 7"0, magnitudes B2=17.94 R2=15.41 I=14.56
