Possible nova in M31

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.

something there

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

single digit SNR

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

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.
