[vsnet-alert 14622] Re: Possible Nova in Oph - PNV J17395600-2447420

[Terry Bohlsen]

This is interesting
I have also taken 2 spectra of this star , 2 and 4 days earlier also taken 
with a LISA spectrograph.
I have overlaid Christian's spectra over mine from 23/4 at the bottom of the 
page here
http://users.northnet.com.au/~bohlsen/Nova/novaoph.htm

There is a continuing strengthening of the Ha line and the Hb line is 
slightly stronger.

Cheers
