We report the discovery of an optical nova candidate in M 31 on a 12x60 s stacked R filter CCD image obtained with the robotic 60cm telescope with an E2V CCD (2kx2k) of the Livermore Optical Transient Imaging System (Super-LOTIS, located at Steward Observatory, Kitt Peak, Arizona, USA).
The object was first detected on 2008 Feb 07.17 UT with a magnitude of 18.2 and is clearly visible on several of the individual 60 s images. The position for the nova candidate is RA = 00h42m30.40s, Dec = 41d09'53.9" (J2000, accuracy of 0.3"), which is 2'37" west and 6'16" 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 (limiting R magnitude of ~19.0) at the position of the nova candidate on Super-LOTIS images of 2008 Feb 06.17 UT and before. 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).
Erratum: In ATel #1364 the nova candidate is located 2'41" east from the core of M 31 instead of 2'41" west.
