ALPY 600 spectrum of V392 Per in outburst (R~500)

It looks a very strange spectrum to me but I don't really know what to expect for this sort of object !

Found a reference spectrum for this object here from 1998 when it was v mag 17.4. It is ~11 magnitudes brighter than this currently !

Good catch, Robin!
You have been mentioned on Atel#11588 having similar spectrum!

Cheers,
Peter

Confirmed as bright nova

Of course, more spectra are welcome. This one could be fast.

Impressive !

Despite some difference it looks to be similar with SN2017eaw (see survey in that forum).

Many thanks for that alert.

Great catch Robin,

Following the last year work on SN2017eaw a rough and dirty evaluation of your excellent data shows an hydrogène Ha expansion speed around 2600kms.

Everything is going fast and this is already confirmed with more details on http://www.astronomerstelegram.org/?read=11588.

Congratulation and thank again for that alert. An excellent target for Alpy but weather condition are presently difficult here in Toulouse.

I should add that, for SN2017eaw such global pattern arised around 70days after origin (+/-10days). If this is also true here, that mean this outburst is going on since a couple weeks. Interesting to note it has just been discovered despite all attention of astronomers around the world.
