[nova] Spectroscopic confirmation of Possible Nova in Sgr

38.png

We performed low-reslution (R~550) spectroscopic observations of the possible nova in Sgr (= PNV J17474639-2335112 listed in the TCOP of CBAT web page) using Araki telescope and LOSA/F2 at Koyama Astronomical Observatory on 2011 January 28.863UT. Our observations were carried out under the cloudy sky. The spectrum of the object shows prominent emission lines in H-alpha, H-beta and O I (777.4 nm) on a highly reddened continuum light. These features suggest that the object would be a classical nova past the maximum light reddened by interstellar mediums.
