Cluster observations of ∂Bz/∂x during growth phase magnetotail stretching intervals

Cluster observations of ∂Bz/∂x during growth phase magnetotail stretching intervals

We study a statistics of ∂Bz/∂x in a thin stretching current sheet (substorm growth phases) observed by Cluster between 8 and 18 RE downtail. After 2005, spacecraft separation allowed to measure directly this derivative of Bz along the tail axis. The near‐tail events (within 14 RE) exhibited a strai...

Zusammenfassung:We study a statistics of ∂Bz/∂x in a thin stretching current sheet (substorm growth phases) observed by Cluster between 8 and 18 RE downtail. After 2005, spacecraft separation allowed to measure directly this derivative of Bz along the tail axis. The near‐tail events (within 14 RE) exhibited a straight decrease of an initially large positive ∂Bz/∂x to ∼1–2 nT/RE. In the more stretched middle tail, usually the small |∂Bz/∂x|
