[vsnet-outburst 10789] Re: [vsnet-alert 11692] Bright eruptive object in Eridanus

[Hiroyuki Maehara]

 M. Fujii (Okayama, Japan) obtained a low-resolution spectrum
of the object. He reports that the spectrum shows the Balmer 
(FWHM of H_alpha emission is 3200 km/s), He I (447.1, 501.6,
587.6, 667.8, 706.5 nm), N III (464.0 nm), Na I D (589.2 nm), 
O I(777.3, 844.6 nm), and Mg II (823.2 nm) emission lines.

 I also obtained a spectrum of the object which shows broad Balmer,
He I, and N III emission lines. The FWHM of H_alpha emission is 3400km/s.

 These features suggest that this object is a He/N nova.
