V4739 Sgr (Nova Sgr 2001-2) spectroscopic confirmation by Fujii

    M. Fujii (Fujii Bisei Observatory) took the spectrum of V4739 Sgr
on Aug. 28.44 UT.  Both H-alpha and H-beta were seen in broad emission
(FWHM of the H-alpha is 4700 km/s).  There was little evidence of Fe II
lines, and Fujii suggested a He/N-type nova.

    The spectrum is given at:

    Fujii also pointed out similarity of the spectrum with that of the
recurrent nova U Sco during the 1999 outburst
(cf. http://vsnet1.harenet.ne.jp/~aikow/u_sco.GIF)

    Fujii's line identifications:

  N III 4640A
  H-beta
  He I 5015A
  N II 5679A
  He I 5876A
  Na I 5892A (weak absorption)
       5912A
       6170A (weak, broad emission)
  H-alpha
  He I 7065A

Relayed from M. Fujii.
