| Zusammenfassung |
| The multi-probe CLUSTER and THEMIS missions revealed local and system wide aspects of
collisionless fast magnetic reconnection separating spatial and temporal structures in the key
regions of the inner and outer magnetosphere: at the magnetopause, in the cusp regions, in the
near-Earth and mid-tail. The distant tail was studied by single spacecraft missions or
occasionally during fortuitous rare alignment of two spacecraft constellations. For example,
Geotail and IMP-8 observations in the deep-tail revealed, that the tailward progression and
retreat of magnetic reconnection associated activity is highly dynamic, turbulent,
characterized by complex 3D structures, multiple X-lines, appearance and dynamical
evolution of acceleration centers. The first two-probe mission with comprehensive field and
particle instrumentation is represented by ARTEMIS spacecraft P1 and P2 (Angelopoulos
and Sibeck, 2008; Angelopoulos, 2010). These probes were sent to the lunar orbits
(~-60RE) allowing an unprecedented study of magnetic reconnection, turbulence and
magnetotail dynamics in the deep-tail. Since the physical conditions are rather
different in the mid- and distant-tail regions comparative in-situ studies can reveal the
alteration of different regimes of magnetic reconnection under changing conditions
in the solar wind. Here we present the first ARTEMIS observations of magnetic
reconnection associated processes observed by ARTEMIS probes in the deep-tail. |
