More Than 40 Years of Contacts with Boudine

• Philippe Lemaire
• 21 October 2005

2
1962-1965 (Service dAéronomie, 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

3
1966-1968(Service dAéronomie, 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.
• We co-operated
• Lemaire,P., Delaboudinière,J.P., (1968)

  satellite pour l'étude de la chromosphère

  selected

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

  fine structure by means of simultaneous high
  resolution observations of the profile of Lyman
  alpha, Lyman beta, MgII and CaII H and K lines

5
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

6
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

• 1983, Jean-Pierre is member of the LURE SUPERACO
  beam studies to obtain a calibration output for
  UV Astrophysics

8
1986-1992(LPSP/IAS, Verrières le Buisson)

• 1986-1989, we shared the same office
• (Study and realization of a calibration station
  connected to SUPERACO synchrotron ring)

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
