On the basis of spectroscopic CCD material obtained at the Haute Provence O
bservatory, we provide line identifications and equivalent width measuremen
ts in the wavelength region 4095 - 8935 Angstrom of the spectrum of MWC 342
. Two hundred eighty emission features are identified and eighteen absorpti
on features. Nine interstellar bands could be identified. Some of the remai
ning absorption lines correspond to a B0 type star. The cooler emission lin
es correspond to a spectrum of an early A-type star. The temperatures deriv
ed from both spectral types (29 000 and 9 000 K) are in excellent agreement
with the temperatures derived by photometrists.
