Further to CBET 3182, U. Munari and P. Ochner, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova and A. Maitan, S. Tomaselli, and S. Dallaporta, "Asiago Novae and Symbiotic Stars" (ANS) collaboration, report that optical spectra (range 330-800 nm, dispersion 0.231 nm/pixel) of PNV J18193700-1907400 were obtained on July 18.88 UT with the Asiago 1.22-m telescope. The object presents hydrogen Balmer and Fe II lines (multiplets 42, 48, 49, 27, 28, 37, 38) in strong emission, and it is classified as a "Fe II"-type nova close to maximum brightness. Strong interstellar Na I and K I atomic lines and diffuse bands (at 443.0, 578.0, 627.0, 628.4, and 6614 nm) indicates large interstellar reddening affecting the nova. The FWHM of Balmer and Fe II emission lines is 990 km/s; the FWHM of He I lines is 640 km/s. He I lines present marked P-Cyg absorption components blue-shifted by 760 km/s with respect to the emission components. Fe II show much weaker P-Cyg absorptions blue-shifted by 570 km/s, while no P-Cyg component is present in Balmer lines. The absolute fluxes of H_alpha, H_beta, H_gamma, Fe II 492.3-nm, Fe II 501.8-nm, He I 587.6-nm, and He I 667.8-nm, in units of 10**(-13) erg cm**(-2) s**(-1), are 75.0, 5.1, 1.4, 1.7, 2.1, 1.1, and 1.0, respectively. CCD photometry for July 18.92 UT yields V = 12.28, B-V = +1.77, V-R_c = +1.13, V-I_c = +2.27.
