1994A&AS..108..561M

Using the coude spectrograph of the NAO 2m RCC telescope at the Rodopa mountains, Bulgaria, nine spectra in the wavelength range from 3550 to 4800A of P Cygni were obtained during the year of 1985. By averaging these spectra we achieved a S/N -ratio of about 45. Here we present a spectral atlas with complete line identifications. Apart from the lines listed by de Groot (1969) many new lines of OII, NII and FeIII ions are identified. Few lines of NIII and SIII mainly from higher excitation levels are also observed. The most intensive lines of OIII and CIII are seen in absorption. In addition to the forbidden lines discovered by Stahl et al. (1991, 1993) a number of further forbidden lines are identified. A special feature of our spectrum is the appearance of AlIII lines in emission.
