We report the discovery of a possible nova in M 31 on a 12x60s stacked R filter CCD image 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 2010 December 11.095 UT with magnitude of 16.6. The object is visible on all individual images. The position for the nova candidate is RA = 00h42m31.08s, Dec = +41d27'20.3"(J2000, accuracy of 0.3"), which is 149" west and 672" north of the core of M 31.

We do not detect the object on a 4x60s stacked SLOTIS CCD image obtained on2010 December 5.213 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 ).

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).
