The satellite has yielded new information on the arrangement of irregularities in sheets and the structure of plasma resonances in the ionosphere. Studies of the geographical distributions of the different kinds of spread F, sporadic E, and other phenomena will be facilitated by the satellite. More phenomena will undoubtedly be recognized as the records are studied.
