1962-1965 (Service d’Aéronomie, Verrières le Buisson)
• Jean-Pierre preceded me in SA by few months• We have shared (with Roger Bonnet and few
others) the same office during at least one year• Jean-Pierre was already working on absorption
cell (…)• This was the period of Sahara rocket launches

1966-1968(Service d’Aéronomie, Verrières le Buisson)
• We shared (with D. Samain) the same office• Jean-Pierre was preparing ‘Dragon’ rocket to be launched in
the Landes with a solar Helium absorption cell. I was making balloon launches with a solar Magnesium II spectrograph.

satellite pour l'étude de la chromosphère solaire, Rapport interne du Service d'Aeronomie n°167

1969-1971(LPSP, Verrières le Buisson)
• We shared (with D. Samain) the same office• Jean-Pierre has several unsuccessful rocket launches in the
Landes• We were preparing a bi-face rocket experiment on a
Veronique: • One side: solar Helium absorption cell (Boudine)• Other side: solar absolute Mg II lines calibration (D. Sacotte, P.
Lemaire et al)
• OSO8/NASA proposal selected:• Lemaire,P., Vidal-Madjar,A., Vial,J.C., Bonnet,R.M., (1969) Study of the chromosphere
fine structure by means of simultaneous high resolution observations of the profile of Lyman alpha, Lyman beta, MgII and CaII H and K lines

1972-1976(LPSP, Verrières le Buisson)
• 1972, the Veronique rocket launch from Kourou (Guyana) failed (rocket cap not ejected). Then new instrumentations are built for a successful launch from White Sand in 1975
• Use of the LURE ACO synchrotron ring to calibrate D2B optical components
• 1975, OSO8 (June) and D2B (December) are put in orbit• D2B works one year and OSO8 three years and three
months.• D2B solar data (after a sophisticated treatment) are
available as images at several wavelengths in Solar Geophysical Data

1977-1981(LPSP, Verrières le Buisson)
• Jean-Pierre was involved in several proposals to measure the absolute flux of the Sun (DISCO?, ..) and established contacts with several labs in URSS.
• I was involved in several proposals (CNES, NASA), in the development RASOLBA balloon gondola and instrumentation and in OSO8 data analysis

Conclusion
• I have probably missed some important events
• We have survived 4 solar cycles of cooperation and competition
• One meeting point was the visit to the library, every day after lunch, to look at the new scientific magazines on the display unit
• I hope to continue to keep contact with Boudine during many years in the future
