On the basis of spectroscopic CCD material obtained at the Haute Provence
Observatory, we provide line identifications and equivalent width
measurements in the wavelength regions
3750-5112 and of the spectrum of HD 45677. Over 235
features are identified and a comparison of our results with those of other
authors is provided. We also discuss the variability of the lines using
equivalent widths and the line spectrum. We conclude that the gaseous shell
surrounding the star has a temperature of the order of 7000 K and that its
distance to the star is less than ten stellar radii.
We discuss the
similarity of this star to other stars previously analyzed.
