Hi George,
There is another one classified by me last October which was then also confirmed by professionals
https://britastro.org/node/15857
but I dont know of any others.
It would be nice to have a higher SNR spectrum to confirm the presence of other features (eg Fe curtain or He, N lines) but that would need a larger telescope. The spectroscopic evolution of an initial blue continuum with a strong H alpha emission emerging over time with around this velocity is characteristic of a nova though.
Cheers
Robin
