COMPARISON OF THE PREDICTED AND OBSERVED MAGNETIC FIELD AT ATS 1.

The principal features of the quiet-day magnetic field variations at the position of the geosynchronous satellite ATS 1 are compared with the fields predicted by several magnetospheric models. To properly predict the ATS 1 field, the magnetopause model must include ‘tilt’ effects (caused by the changing orientation of the earth's dipole axis with respect to the solar wind direction), and the model of the tail field must allow the neutral sheet currents to return on the magnetopause. Olson's models of the magnetopause and tail fields, which incorporate these features, are used to predict the daily and seasonal field variations at other geosynchronous longitudes. The fields predicted by these models account for most of the observed ATS 1 variations.
