| Zusammenfassung |
| A special high-resolution routine of the
EISCAT radar has been used to investigate the structure and development of the
poleward wall of a deep trough in electron density. The feature was tracked by
the radar during a 7-hour period under very quiet geomagnetic conditions. The
field-aligned nature of the structure enabled an estimate to be made of the
inclination of the geomagnetic field above EISCAT that was in good agreement
with the current model. Observations of narrow field-aligned enhancements in
electron temperature demonstrated that the wall of this trough is a dynamic
feature, reforming regularly as the electron density responds on a time scale of
tens of minutes to energy input from soft-particle precipitation. |
