We report the discovery of a possible nova in M31 on four consecutive
dithered stacked R filter CCD images, obtained on 2007 September
02.09, 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 13.5µm sq. pixels). The R magnitude of the
object was 18.1. On 2007 September 03.09, the object was again
detected with the same instrument setup, with an R magnitude of 18.2.
A stacked image from 2007 August 16 shows no object at the position of
the nova candidate brighter than the limiting R magnitude of ~20.5.
All magnitudes given are from a photometric solution using R
magnitudes of the Massey M31 catalog. The position obtained for the
nova candidate is RA(2000) = 00h 42m 29.397s, Dec(2000) = +41° 18'
24.84" with an accuracy of 0.1".
