V5584 SAGITTARII
     Ashish Raj, N. M. Ashok, and D. P. K. Banerjee, Physical Research
Laboratory, report near-infrared J-, H-, and K-band spectroscopy of the nova
V5584 Sgr (cf. IAUC 9089) obtained with the Mt. Abu 1.2-m telescope (+ PRL
Near-Infrared NICMOS3 Imager/Spectrometer) on Oct. 29.58 and Nov. 3.59 UT.
The Oct. 29 spectra show H I Paschen and Brackett lines with strong P-Cyg
profiles.  Prominent O I lines, C I lines, and N I lines are also seen,
accompanied by P-Cyg profiles.  The Gaussian FWHM of the absorption and
emission components of the Paschen_beta line are 400 and 560 km/s.  The
separation between the absorption and emission peaks, as estimated from
various lines, is typically in the range 550-650 km/s.  The spectra taken on
Nov. 3.59 show considerable strengthening of the emission components, while
the P-Cyg absorption components are present but at reduced intensity.  The
recorded infrared spectra of V5584 Sgr are typical of the Fe II class of
novae.
      Visual magnitude estimate by K. Hornoch, Vohancice, Czech Republic:
Oct. 31.724 UT, 9.5.
