On the eve of the total eclipse of the sun on July 11th, 1991 our reporter Nina Morgan describes the preparations made for this event at one of the world’s best observatories, the Mauna Kea telescopes in Hawaii. This eclipse marks the first test of the concept of the Keck telescope lens using a segmented mirror ten meters in diameter. The Netherlands, Britain and Canada made observations at Mauna Kea using their JCMT telescope.
