Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova? .(mag.= 17.9) in M31 on nine 40-s unfiltered CCD frames taken around 2013 Oct. 31.4963 UT, ( limiting magnitude = 19.4 ) 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 2013 Oct. 29.571 UT (limiting magnitude = 19.2) and Oct 30.666 UT (limiting magnitude = 19.5). . 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 18.4). the nearest star in M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 04s79, 31."2, distance 0."8, magnitudes V=22.5, B=23.6, R=22.0
