| Zusammenfassung |
Thirteen events of high-latitude ionospheric
travelling convection vortices during very quiet conditions were identified in
the Greenland magnetometer data during 1990 and 1991. The latitudes of the
vortex centres for these events are compared to the energetic electron trapping
boundaries as identified by the particle measurements of the NOAA 10 satellite.
In addition, for all events at least one close DMSP overpass was available. All
but one of the 13 cases agree to an exceptional degree that: the TCV centres are
located within the region of trapped, high energy electrons close to the
trapping boundary for the population of electrons with energy greater than
>100 keV. Correspondingly, from the DMSP data they are located within the
region of plasmasheet-type precipitation close to the CPS/BPS precipitation
boundary. That is, the TCV centres map to deep inside the magnetosphere and not
to the magnetopause.
