1956 - International Geophysical Year
1958 - Installation of the large prism-grating spectrometer
1963 - Double pass on the grating
Inside the spectrometer : the grating
• 1956 M. Migeotte, L. Neven and J.W. Swensson : The Solar Spectrum from 2.8 to 23.7 microns. Analog data.
+ table of Measures and Identifications (1957).
• 1963 L. Delbouille, G. Roland : The Solar Spectrum from 7498 to 12016 Å + table of Measures and Identifications J.W. Swensson,

1965 Installation of double pass at Kitt Peak
1966 First digital computer – DDP 224
1967 Newtelescope
Freons and Ozone
1974 Publications of Molina and Rowland, Stolansky and Cicerone.
1975 first identification of HF absorption in balloon spectra.
1977 confirmation of the possibility to observe it from the Jungfraujoch.
The observations for the solar “visible” Atlas being complete, the spectrometer is equipped with a grating for longer wavelengths.
The “atmospheric” measurements now have priority.
