Letter from Thomas Gold to Dr Riccardo Giacconi, Center for ASTrphysics, Harvard College Observatory, 60 Garden STreet, Cambridge, Massachusetts Has an interest in the solar flare program of NASA. Would be chiefly interested in X-ray images and their interpretation. Asks if Giacconi is arranging for such experiments on the proposed Solar Maximum Mission, as Gold would be most interested; possibly Giacconi would even consider sime mention of Gold's interest in any proposal he may prepare. Gold would be happy to co-operate in any way he can. 6 March 1974
