| Zusammenfassung |
| In this research, the properties of a tail current sheet, which has a flattened geometry, and its
evolution during substorm activity have been investigated. The geometrical configuration of
the magnetic field and the spatial distribution of the current density in a flattened current sheet
have been revealed with certainty for the first time. It is found that such a flattened current
sheet has sufficiently strong By (GSM) within its neutral sheet that the magnetic field
lines (MFLs) in the neutral sheet are lie almost in the GSM equatorial plane and
that the normal directions are generally northward. Detailed analyses show that,
the magnetic field lines are spiral-like, not plane curves, which are left-handed or
right-handed spiral for By>0 or By |
