We report the discovery of a possible nova in M31 on an rgb and an unfiltered CCD image (2006, April 26.273, 15.9 mag; 28.263, 16.1 mag) obtained with the Bradford Robotic Telescope Galaxy at the Tenerife Observatory (365mm, f/11 Schmidt-Cassegrain telescope with a 0.67 focal reducer with a FLI MaxCam ME2 1k x 1k CCD camera with 13Mu sq. pixels). The position obtained for the nova candidate is RA = 00h 43m 13.38s, Dec = +41° 16' 58.9" with an accuracy of 0.3". At the position of the nova candidate no star brighter than 17.5 mag was detected on 2006, March 12.865 on a Bradford rgb image. Recent unfiltered observations on May 7.154 with a 35cm f/10 Schmidt-Cassegrain telescope with an SBIG STL-1001 1k x 1k CCD camera with 24mu sq. pixels of the Observatori Astronomic de Mallorca OAM (620), Costitx, Spain show no object brighter than 17.3 mag at the position of the nova. All magnitudes given are from a photometric solution using R magnitudes of the USNO-B1 catalog.
