| Zusammenfassung |
| One of the factors which affect the solar wind–magnetosphere interaction is the orientation of
the interplanetary magnetic field (IMF). The very rarely observed radial IMF results in
magnetopause locations up to several radii farther away from the Earth than predicted and
causes a specific magnetopause shape. We present a case study of magnetopause crossings
which were observed by the THEMIS spacecraft and analyze the difference between
observed magnetopause positions and those which are predicted by an empirical
magnetopause model. We use both the data (if available) from the L1 point and from
near-Earth solar wind monitors as a model input. We discuss a role of the long-lasting
radial IMF orientation on the magnetopause position and the influences of other
parameters such as the dynamic pressure and IMF BZ component at different local times. |
