[vsnet-alert 19122] Re: spectroscopic confirmation that ASASSN-15qd is a nova

[Hiroyuki Maehara]

Fujii-san obtained a low resolution spectrum of this object.
http://otobs.org/FBO/etc/asassn-15qd.png

The spectrum shows a strong H-alpha emission line with a FWHM of ~1600 km/s.
O I 7773, Ca II 8251 (and/or Mg II 8232), O I 8446 and Ca II 8498 lines are 
also in emission (ATel #8127).
