We report the discovery of a possible nova in the disk of M 31 on two 4x200s stacked R filter CCD images, obtained with the the 80 cm Ritchey-Chretien F/9.6 Joan Oro telescope at Observatori Astronomic del Montsec, owned by the Catalan Government and operated by the Institut d'Estudis Espacials de Catalunya, Spain, using a Finger Lakes PL4240-1-BI CCD Camera (with a Class 1 Basic Broadband coated 2k x 2k chip with 13.5 microns sq. pixels). The new candidate was detected on 2014 July 08.05 UT and 09.06 UT with R magnitudes of 18.0±0.1 and 17.7±0.1, respectively. Its position is RA = 00h42m54.72s, Dec = +40o56'33.5" (J2000, accuracy 0.35"), which is 118" east and 1176" south of the core of M 31. These were the first observations of our M 31 disk monitoring and there are no previous images of this field with the same telescope. However, no object is visible on the images of the Local Group Galaxies Survey (LGGS, Massey et al. 2006, AJ, 131, 2478). Furthermore, 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 were obtained from a photometric solution using R magnitudes of the LGGS (Massey et al. 2006). Spectroscopic follow-up observations are encouraged.
