NOVA SAGITTARII 2014 = PNV J18250860-2236024
     Syuichi Nakano, Sumoto, Japan, reports the discovery by Sigeru Furuyama
(Tone-machi, Ibaraki-ken, Japan) of a possible nova (mag 8.7) in Sgr on two
10-s CCD frames (limiting magnitude 12.5) taken on Jan. 26.857 UT using a
200-mm f/2.8 camera lens + BJ-42L camera; the position provided for the new
object is R.A. = 18h25m08s.60, Decl. = -22d36'02".4 (equinox 2000.0), and
Furuyama added that nothing was visible at this position on his numerous
patrol frames of the same field taken since 2012 August.  The variable was
designated PNV J18250860-2236024 when it was posted at the Central Bureau's
TOCP webpage.  Additional CCD magnitudes for PNV J18250860-2236024:  Jan.

the following visual magnitude estimates for PNV J18250860-2236024:  Jan.
28.839, 10.5; Feb. 8.834, 10.9.

     Akira Arai, Nishi-Harima Astronomical Observatory, University of Hyogo,
reports that a low-dispersion spectrogram (R about 980 at 650 nm) of PNV
J18250860-2236024 was obtained on Jan. 30.87 UT using the 2-m Nayuta telescope
(+ MALLS) at the Nishi-Harima Astronomical Observatory.  The spectrum shows
emission lines at H-alpha (FWHM about 1200 km/s; EW about -70 nm), H-beta (EW
about -13 nm), Na D, Fe II (multiplets 42, 48, 49, 55, 74), [O I] (557.7-
630.0-, and 636.4-nm), O I (777.3- and 844.6-nm), and the Ca II infrared
triplet on a highly reddened continuum emission.  Tiny absorption features are
seen with the H-alpha and O I lines at about -1200 and -700 km/s,
respectively.  These results indicate that the object is a "Fe II"-type
classical nova past maximum.  Double-peaked profiles are seen clearly in the
H-alpha and O I lines.  Bluer peaks were located at the rest wavelength for
these lines.  The peak separation of the H-alpha feature is about 650 km/s,
and V/R about 0.9.  For O I lines, peak-separations and V/R are about 700 km/s
and about 0.5, respectively.
