My spectrum of this unusual outburst, taken using an ALPY 600.

A strange looking spectrum to me. Can anyone interpret it ?

 

Cheers

Lookes like a late type star

Lookes like a late type star with H-alph in emission.  That is completely consisent with a Dward Novae, no?

Classical Nova

Not really. The lines are very broad (~2600km/s) and show PCygni profiles.  It turned out to be a rare event when a known dwarf nova turned into a classical nova. The red continuum is due to high IS extinction. The spectrum was referenced in this paper

Here  are my further spectra of this object taken over the past 3 weeks (link to the BAA Spectroscopy database)
