We report the discovery of a possible nova in the outer disk of M 31 on two 15x60s and 7x60s 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 February 15.127 and 18.121 UT with magnitude
of 18.7 and 18.0, respectively. The position for the nova candidate is RA = 00h42m02.33s, Dec = +41d29'15.6"(J2000, accuracy of 0.3"), which is 473" west and 787" north of the core of M 31.
We do not detect the object on a 10x60s stacked SLOTIS CCD image obtained on 2011 February 6.148 UT (limiting R magnitude at the position of 19.5).
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 ).
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).
