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 ▲]

Comet 1959 k has been observed spectrographically at the coudé-focus of the 193 cm-reflector of OHP. Fairly high resolutions have been used. The continuum is weak and confined into a small central region. The structures of the OH -, NH -, C3 - and CH bands show greater detail than on any hitherto described cometary spectrogram. The R-branches of the (0 - 0) and (0 - 1) bands of the blue system of CN have been resolved. The Swings - and Greenstein effects have been discussed for CN (0 - 0). The rotational structure of the Swan bands is partly resolved. [less ▲]

Aux distances héliocentriques inférieures a 0,6 U. A., le spectre d'émission de la comète 1956h montre un doublet D anormalement intense. L'intensité du continuum est toujours élevée. On a obtenu une plus grande precision pour les longueurs d'onde des émissions jaunes-rouges ; celles-ci appartiennent toutes aux transitions (o, v2', o) → (o, o, o) de NH2 pour 5 ≤ v2' ≤ 10, les branches Q étant les mieux marquées.
