Scientific paper

We present a sample spectral atlas and identification list of the unusually variable object MWC 560 for the region 3600 A-4930 A at two stages of ejection activity: (a) discrete ejections during January-April 1990 with velocities of a few thousands km/s, and (b) quasi-stationary ejections during September 1990-April 1991 with velocities of a few hundreds km/s. The atlas is based on spectra obtained with the coude-spectrograph of the 2-m telescope at Bulgarian National Astronomical Observatory. About 400 lines of 22 species are identified. Estimations of the relative intensities, FWHM, and equivalent widths of the emission and absorption lines are given.
