Abstract (from CDS):

E. Mason, A. Ederoclite, L. Germany, and F. Salas, European Southern Observatory, Santiago; and M. Della Valle, Istituto Nazionale di Astrofisica, Arcetri/Firenze, report that echelle spectra (390-900 nm; resolution 48000) of V2574 Oph (cf. IAUC 8323), obtained on Apr. 17.32 and 18.37 UT at La Silla with the 2.2-m telescope (+ Fiber-fed Extended Range Optical Spectrograph), are dominated by H_alpha, Na D, and Ca II(2) emission lines, which are flanked by double P-Cyg profiles. From the minima of the P-Cyg absorptions, the measured expansion velocities are about 400 and 1050 km/s for H_alpha and 400 and 1000 km/s for Na D. Emission lines of Fe II (42, 49, and 74) and O I (multiplet 1) were also detected. The overall appearance of the spectra indicates a substantial evolution with respect to the description provided on IAUC 8324, suggesting that this is a slow nova caught at maximum or slightly before maximum light.
