Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report the discovery of a possible nova .(mag.= 15.6) in M31 on seven 40-s unfiltered CCD frames taken around 2013 Jan. 26.42700UT, ( 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 Jan. 20.421 UT (limiting magnitude = 19.1). and Jan. 23.420 UT (limiting magnitude = 19.1) . 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 18.9) 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 01s92, 39."7, distance 4."8, magnitudes V=16.1, B=17.0, R=15.7

Mag.= 15.7, position end figures 02s.05, 44".0 observed by T. Noguchi, Chiba-ken, Japan, from a stacked image (limit mag.= 18.0) exposed by each 50-s x 4 frames using 0.23-m f/6.3 Schmidt-Cassegrain + unfiltered CCD. Position and magnitude were measured using UCAC3. See an image at http://park8.wakwak.com/~ngc/images/PNVinM31_20130127.jpg.

PNV observed at coordinates 00 44 02.03 +41 25 43.6 (UCAC3). Magnitude 17.4 U +/- 0.2 . Limiting magnitude 19.5 . Sum of 3 x 240-sec images. Nothing visible at these coordinates except galaxy background on DSS. Observer: R. A. Koff, Antelope Hills Observatory, Bennett, Colorado USA (H09).
