Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova or var.TCP J00403295+4034387(mag.= 18.3) in M31 on seven 40-s unfiltered CCD frames taken around 2011 Nov. 14.53770 UT,( limiting magnitude = 20.0 ) using a Meade 200R 0.40-m f/9.8 reflector (+SBIG STL1001E camera). (reference catalogue USNO B1.0) as follows Nothing is visible at this location on our past frames taken on 2011 Nov. 03.527 UT (limiting magnitude = 19.8) and Nov. 07.493 UT (limiting magnitude = 19.6). 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 18.5) and 1993 Sep. 23(limiting infrared mag 18.1). the nearest star in M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 32s97, 39."0, distance 0."4, magnitudes V=20.5, B=20.4, R=20.4
