Taguchi, and O. Hashimoto, Gunma Astronomical Observatory (GAO), write that a low-resolution spectrum (range 420-800 nm; resolution 1.0 nm), obtained with the GAO 1.5-m telescope (+ GLOWS) on Dec. 15.4 UT, confirms that the object announced on CBET 2075 is a nova, showing H_alpha emission (FWHM about 1000 km/s) with a P-Cyg profile, its absorption minimum being blue-shifted by 1000 km/s with respect to the emission peak. H_beta, H_gamma, and Fe II (multiplet 42) lines also have P-Cyg profiles. U. Munari, Istituto Nazionale di Astrofisica, Padova Astronomical Observatory; and P. Valisa, Asiago Novae and Symbiotic Stars (ANS) collaboration, report that their spectroscopy (range 390-860 nm, dispersion 0.22 nm/pixel; range 544-704 nm at 0.072 nm/pixel) with the Varese 0.6-m telescope on Dec. 15.8 UT shows that this object is indeed a nova, of the Fe II type, with Balmer and Fe II lines in emission and displaying P-Cyg profiles. Strong interstellar lines and diffuse interstellar bands suggest a high reddening. The absorption component of the Balmer P-Cyg line profiles has a FWHM of 560 km/s and is displaced by -620 km/s with respect to the emission component, whose FWHM is 1025 km/s. Fe II multiplets 42 and 49 are in emission with P-Cyg profiles, too. The H_alpha/H_beta flux ratio is 5.7, and H_alpha has an equivalent width of 0.69 nm. The continuum is characterized by the deep absorption lines characteristic of novae close to their maximum brightness. Visual magnitude estimate by K. Hornoch, Ondrejov, Czech Republic: Dec. 15.700 UT, 10.4. NOTE: These 'Central Bureau Electronic Telegrams' are sometimes superseded by text appearing later in the printed IAU Circulars.
