Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of Transient object .(mag.= 18.9) in M31 on three 40-s unfiltered CCD frames taken around 2012 Oct. 18.68373 UT, ( limiting magnitude = 19.9 ) and mag=18.6 Oct. 19.507 UT, 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 2012 Oct. 14.556 UT (limiting magnitude = 19.8). and Oct. 15.519 UT (limiting magnitude = 19.8) . 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 19.0) and 1993 Oct. 21(limiting infrared mag 18.8). the nearest star in M31 catalogue (http://www.lowell.edu/users/massey/lgsurvey.html) has position end figures 28s50, 02."9, distance 7."6, magnitudes V=21.7, B=21.7, R=21.6 this object is very near Nova M31 2011-10e and 2008-12a (Pietsch catakog) http://www.mpe.mpg.de/~m31novae/opt/m31/index.php?lang=en
