Spotted on Friday 13th at mag 16.6
After 24 hours near to mag 16.0
May be a tough one for spectroscopy being quite close to the core.
Possible nova in M31

There is a possibility of some clear sky here tonight but yes,likely to very tricky with interference from galaxy and moonlight
Well after 140 mins on it with the ALPY 600 last night there is something there.
(signs of a broad H alpha emission by the looks) Lets see if I can extract it
Well H alpha is there with the right sort of width for a nova (FWHM ~2500km/s) and probably H beta with similar width but the bright sky background has dragged the SNR down to single digits so nothing else is showing above the noise.
Amazing that you can get a spectrum at all that close to the bright core. I had my first chance to image it last night and it seems to have faded quite a lot.
Confirmation as a nova:
