Abstract:

We report the detection of seven recent nova candidates in M 31 on two sets of three 300 s dithered stacked CCD images obtained on 2010 Oct 4 with the 1.3m Ritchey Chretien f/7.5 telescope at Skinakas Observatory, Crete, Greece, using an Andor DZ436-BV CCD Camera (with a Marconi 2k x 2k chip with 13.5 microns sq. pixels) and a broad (75 Angstrom wide) H-alpha filter. Only novae M31N 2010-07a and M31N 2010-10a were also detected on four 100 s dithered stacked CCD images obtained on 2010 Oct 5 with the same telescope and camera using a R filter.
