PNV J18250860-2236024 2014 01 26.857 * 18 25 08.60 -22 36 02.4 8.7 U Sgr 1 1

Discovered by S. Furuyama, Ibaraki-ken, Japan, on two frames using 200-mm f/2.8 lens + CCD under the limiting magnitude = 12.5, who writes nothing is visible on twenty or more frames taken since 2012 August using same patrol camera and also says T. Noguchi has confirmed this PNV around Jan. 27.8 UT.

Mag.= 9.6, position end figures 08s.76, 02".6 (refer to UCAC4 catalog) observed by T. Noguchi, Chiba-ken, Japan, from a 10-s frame using 0.23-m f/6.3 Schmidt-Cassegrain + unfiltered CCD. An image posted at http://park8.wakwak.com/~ngc/images/PNVinSgr.jpg.

Photometry results of this PNV were V=10.19, R_c=9.72 and I_c=9.15 from CCD images taken with 0.25cm Schmidt–Cassegrain telescope and Apogee Alta E47 CCD camera at Kamagaya, Japan. TYC-6857-437-1 was used as a comparison. (Seiichiro Kiyota).

Mag.= 10.7, position end figures 08s.74, 02".9 (refer to Tycho-2 and GSC-ACT catalogs, respectively) observed by K. Kadota, Saitama-ken on a frame stacked twelve 4-s frames using 0.25-m f/5.0 reflector + unfiltered CCD. Image posted at http://members.jcom.home.ne.jp/kenic-k/image/PNVinSgr-20140202.jpg.

We obtained a low-dispersion spectrum (R about 980 at 650 nm) of the object, using 2m Nayuta telescope (+MALLS) at the Nishi-Harima Astronomical observatory, Japan. The spectrum show 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, 636.4-nm), O I (777.3, 844.6-nm) and Ca II infrared triplet on the highly reddened continuum emission. A tiny absorption features are seen with the H-alpha and O I lines at about -1200 km/s and about -700 km/s, respectively. These results indicate that the object would be a Fe II-type classical nova post the maximum.
