Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova (mag.= 18.9) in M31 on seven 60-s unfiltered CCD frames taken around 2016 Nov. 01.51012 UT, ( limiting magnitude = 19.9 ) using a 0.50-m f/6.8 reflector (+FLI 1001E camera). as follows We report that this star locates 2527" west and 2831" sourth from the center of galaxy. Nothing is visible at this location on our past frames taken on 2016 Oct. 24.597 UT ( limiting magnitude = 20.1 ) and Oct. 29.511 UT ( limiting magnitude = 19.9 ). We have checked in Minor Planets. Nothing is visible at the position of possible nova on the Digitized Sky Survey (POSS2/UKSTU) from 1989 Oct. 01 (limiting red mag 19.1) and 1993 Sep. 23 (limiting infrared mag 18.9). the nearest star in M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 00s84, 57"1, distance 7"9, magnitudes V=22.5, B=22.7, R=22.5,
