We report the discovery of a possible nova in M 31 on two 12x60s stacked R filter CCD images obtained with the robotic 60cm telescope with an E2V CCD (2kx2k, 13.5 microns sq. pixels) of the Livermore Optical Transient Imaging System (Super-LOTIS, located at Steward Observatory, Kitt Peak, Arizona, USA). The object was first detected on 2009 November 6.26 and 8.26 UT with respective magnitudes of 19.3 and 18.5. The position for the nova candidate is RA = 00h43m10.49s, Dec = +41d12'18.3"(J2000, accuracy of 0.4"), which is 295" east and 231" south of the core of M 31. All magnitudes given are obtained from a photometric solution using R magnitudes of the Local Group Survey M 31 catalogue (Massey et al. 2006, AJ 131, 2478). No object is visible at the position of the nova candidate on a Super-LOTIS image of 2009 November 4.26 UT (limiting R magnitude at the position of 19.0). There is no entry in VizieR/CDS for this object and no minor planet could be found on this position using the MPC/IAU Minor Planet Checker (see http://scully.harvard.edu/~cgi/CheckMP ).
