Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova .(mag.= 18.2) in M31 on seven 40-s unfiltered CCD frames taken around 2014 Sep. 08.60993 UT, ( limiting magnitude = 19.2 ). And observe this PN mag=17.5 Sep. 08.818. using a Meade 200R 0.40-m f/9.8 reflector (+SBIG STL1001E camera). as follows Nothing is visible at this location on our past frames taken on 2014 Jul. 27.793 UT (limiting magnitude = 19.4) and Jul 28.786 UT (limiting magnitude = 19.2). . We have checked in Minor Planets. Nothing is visible at the position of possible nova on the Digitized Sky Survey(POSS2/UKSTU) from 1986 Nov. 27 (limiting red mag 18.7) and 1993 Oct. 21(limiting infrared mag 17.9). the nearest star in M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 23s53, 26."4, distance 2."3, magnitudes V=22.1, B=23.6, R=21.3
