| Zusammenfassung |
| We present riometer and in situ observations of a substorm electron
injection on 27 August 2001. The event is seen at more than 20 separate
locations (including ground stations and 6 satellites: Cluster, Polar,
Chandra, and 3 Los Alamos National Laboratory (LANL) spacecraft). The
injection is observed to be dispersionless at 12 of these locations.
Combining these observations with information from the GOES-8 geosynchronous
satellite we argue that the injection initiated near geosynchronous orbit
and expanded poleward (tailward) and equatorward (earthward) afterward.
Further, the injection began several minutes after the reconnection
identified in the Cluster data, thus providing concrete evidence that, in at
least some events, near-Earth reconnection has little if any ionospheric
signature. |
