Abstract:

We report the discovery of an optical nova candidate in the outer disk of M 31 on nine stacked R filter images (each with 60 sec exposure) and four stacked 12nm H-alpha filter images (each with 120 sec exposure) on 2007 Aug 24.081 and 24.093 with a magnitude of 18.7 in R and 18.1 in H-alpha, respectively. The images were obtained at the 60cm f/3 Ganymed telescope located at Skinakas Observatory, Crete, Greece, using a STL11000M CCD Camera.
