discovery of a possible nova .(mag.= 17.4) in M31 on seven 40-s unfiltered CCD frames taken around 2011 Dec. 27.44766 UT, ( limiting magnitude = 19.6 ) 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 Dec. 23.490 UT (limiting magnitude = 19.6). and we find Dec. 26.469 UT (limiting magnitude = 19.4) prediscovary mag 18.2.. 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 55s76, 31."0, distance 4."6, magnitudes V=23.2, B=23.6, R=22.2 Nishiyama & Kabashima

detected on (13, 13, 10, 14, and 9) x 60s stacked R filter CCD images obtained with the robotic 60cm telescope with an E2V CCD (2kx2k, 13.5 micron sq. pixels) of the Livermore Optical Transient Imaging System (Super-LOTIS, located at Steward Observatory, Kitt Peak, Arizona, USA) on 2011 December (24.129, 25.152, 26.149, 27.178, 28.150) UT with magnitude (19.2, 18.5, 18.1, and 17.5), respectively. Position end figures 55s.83, 26".6 (error 0.2"). W. Pietsch, K. Lutz, M. Henze, V. Burwitz (Max-Planck-Institut fuer extraterrestrische Physik), A. Kaur, D.H. Hartmann (Clemson University), G.
