Observatory - GA describes his observation of the projection of a star on the moon's disk: 'Now imagine that you see the moon's limb well, and that you see the star well, with all its rings... The moon approaches the star - goes right over it...the outermost ring of the star considerably within the moon's limb - till when it is satisfied with shewing itself in this ridiculous manner puff it goes out - like a candle...what is one to make of all this?'
