[vsnet-alert 15779] Re: PNV J19150199+0719471: early superhumps?

[Thierry Garrel]

Hi
Low resolution spectra taken by Thibault de France yesterday show  h alpha
in emission not corresponding to a classical nova.
http://www.hd182989.info/nova
Intermediate resolution échelle spectra  were taken from IAC80 Teide show a
double peak h alpha emission line with carbon lines in emission.

It seems not to be classical nova spectra.
Cheers
