We report the discovery of a possible nova in M31 in Liverpool Telescope (LT; Steele et al. 2004) IO:O data taken on 2014 November 7.98 UT.
This potential nova was discovered in observations taken while following the decline of the nearby M31 nova PNV J00423972+4120117 (see ATel #6563, #6616).
We measured the position of this new transient to be RA = 0:42:52.76 Dec. = +41:17:19.7, with an accuracy of 0.2''. The possible nova had a V-band magnitude of 19.03 ± 0.04 on November 7.98 UT and an r'-band magnitude of 19.02 ± 0.03 on November 7.99 UT.
The possible nova is also visible in a second epoch of LT data taken on November 8.11 UT, when it had a magnitude of V = 19.00 ± 0.05 and r' = 18.84 ± 0.03 on November 8.12 UT. The source is not visible on frames taken 2014 October 17.04 UT down to a V-band limiting magnitude of 20.4.
