Spectrograms of HD 108 covering a wide spectral range (3200 Å-8000 Å) have been obtained in 1971 and 1972 at the Haute Provence Observatory. They are described in detail in the present paper and they are compared to previously published observations. New emission lines have been detected (3806 Å, 4415 Å, 4417 Å, 6340 Å) as well as new rapid intensity variations (He I: 4026.2 Å, 4387.9 Å; N III: 3s4P0-3p4D and 42F0-52G; Si IV: 4s2S-4p2P0). The measured radial velocities are compatible with an expanding atmosphere which exhibit a marked acceleration toward the outer layers. [less ▲]
