Wind Observations of Long-Duration High-Speed Flows in the Distant (Xgse= -90 Re) Magnetotail

In February, 2001, the Wind spacecraft resided more than 3 days in the distant magnetotail along its dawn-dusk trajectory. Long-duration (several hours) convective flows up to 800 km/s were frequently detected. Most of the fast flows were directed tailward, although intervals of earthward flows also occurred. The flow reversals may indicate the passage of a reconnection X-line or of a plasmoid. We present detailed particle distributions of the fast flows and discuss their possible sources.
