30 June 1973: 1973 Eclipse and Concorde

From: Julio Bueno To: Multiple recipients of list Subject: Eclipse in 1973

Does anybody have information about a Concorde flight which followed the shadow of an eclipse in 1973??? I was a child when I heard something about it. I remember that this eclipse elapsed about 3 hours for that passengers ... I think that it was a fantastic trip. Julio Cesar Bueno

The flight was on an experimental model Concorde; since it was on its last flight they could chop a hole in its roof to put in an upward-facing window so that the instruments could see the eclipse. They flew from the Canary Islands to Chad and had 73 minutes of totality. Only professionals were aboard. There was an article about the flight in Sky and Telescope in late 1973 or early 1974.

The Concorde traveled along the totality path of the June 30, 1973 eclipse and managed to stay within the Moon's umbra for approximately 74 minutes. Hence, for those on board, there was a totality that lasted about 1 hour and 14 minutes as opposed to the maximum of 7 minutes 04 seconds for a stationary observer at ground level! -- joe rao

Of course. . . I should also have mentioned in my remarks about the Concorde flight in 1973, that all the windows on the aircraft were utilized by equipment used to record the event. I don't think the occupants inside the aircraft saw much (if any) of this record-setting eclipse! -- joe rao

Must be pretty impressive/scary to see total eclipse from ground plus get the supersonic bang at midtotality :-) Olivier R. Staiger HIGH MOON Geneva, Switzerland [email protected] http://eclipse.span.ch phone +41.79.449'4630

For more information on the 1973 Concord flight, I would recommend the video Eclipse 73 available from the Service du film de recherche scientifique, http://www.sfrs.fr

This 35 minutes black and white film describes both the flight and the experiment that were performed aboard the Concord. There are some memorable shots: the edge of the Moon's shadow as it slowly overtakes the plane despite its speed of Mach 2. There is also a short clip of some time lapse photography of the corona taken over the 74 minutes totality period.

It is available in French, English or Spanish. Jean Marc Lariviere

Dear Jean Marc, I tried to go into the website you gave for the Concorde film:

> For more information on the 1973 Concord flight, I would recommend the video Eclipse 73 available from the Service du film de recherche scientifique, http://www.sfrs.fr

The explorer gave me twice a general protection fault, while with other applications it does work. Would it be possible giving me some more details where and how I can order this video and what the price is?

By the way: I have decided yesterday me and Joanne will be going to the Paris exhibition the weekend of 9 and 10 January. I do remember you asking for a catalog (299 FF). Do you still want that catalog and shall I buy it for you? Best regards, Patrick

Bonjour Patrick, I'll get more info about the film Eclipse 73 to you in the coming days. For the time being the SFRC coordinates are as follows: 96 boulevard Raspail, 75272 Paris, Cedex 06. Tel: 01-42-22-46-44 Fax: 01 42 22 93 50 E-mail: [email protected]

The link to SFRC works fine in Netscape so it is rather strange you had some problems in Explorer.

As for the catalog to the Bibliothèque national de France's exhibit FIGURE DU CIEL, I have already put in an order, but thanks for the offer. I hope you enjoy your visit. I'll post information about eclipse representations in this forum the minute I get the catalogue, unless someone else is lucky enough to see it first hand before then. Jean Marc Lariviere

Dear Jean-Marc and Patrick: Have you tried I.N.A. - Institut National de l'Audiovisuel? They seem to have almost everything that's ever been on French TV or French newsreels.
