Scientific paper

We report on the detection of three recent nova candidates in M 31 on a set of 3x300s dithered stacked CCD images obtained on 2011 July 14 with the 1.3m Ritchey Chretien f/7.5 telescope at Skinakas Observatory, Crete, Greece, using an Andor DZ436-BV-9CQ CCD Camera (with a Marconi 2k x 2k chip with 13.5 microns sq. pixels) and a broad (75 Angstrom wide) H-alpha filter. The most recent one of these candidates (PNV J00430685+4115308 = M31N 2011-06d(?)) is also detected on 4x300s stacked R filter images taken on July 15 with the same telescope.
