E. Mason, European Southern Observatory (ESO); A. Brandeker, Department of Astronomy and Astrophysics, University of Toronto; A. Ederoclite, ESO; and M. Della Valle, Istituto Nazionale di Astrofisica, Osservatorio di Arcetri, confirm that the new object discovered by Liller is a classical nova in outburst. An echelle spectrogram (range 420-840 nm) of the nova was taken on Aug. 8.17 UT with the ESO New Technology Telescope (+ EMMI). A preliminary analysis shows that the spectrum is dominated by Balmer, Fe II (42 and 74), and Na I (1) emission lines. The H_beta emission line appears as strong as the H_alpha line. The line profile of the Balmer emissions is very broad and slightly asymmetric with a stronger blue peak. The average FWHM measured on the Balmer lines is about 3200 km/s. There is a marginal evidence of a P-Cyg absorption on the blue wing of the H_beta emission, which possibly indicates an expansion velocity of about 2100 km/s.
