Abstract : A radiotelescope designed to operate in the Mband frequency region (50 kmc - 75 kmc) was constructed on the roof of the Columbia University Physics Building in 1959. This radiotelescope, with its 5-foot parabolic antenna, was used to study atmospheric absorption lines which are members of the O(2) spin reorientation spectrum and which are abundant near 60 kmc. It was also used to study the emission line near 53 kmc produced by the hyperfine splitting of hydrogenic nitrogen ions in the solar corona. (Author)
