Magnetic reconnection in the Earth's magnetotail plays a key role in controlling the dynamics of the Earth's magnetosphere. Recent results based on Cluster multi-spacecraft analysis have raised important questions about the traditional interpretation of reconnection-associated phenomena observed by single spacecraft. Cluster has shown that observations conventionally interpreted as a single X-line can correspond to multiple X-line structure [1]. Single point observations cannot distinguish between these two possibilities, and previous interpretations have invoked the simpler picture. This case study is put into a wider context by examining the plasma dynamics following this particular event. Within this picture, one can make the hypothesis that further loop-like structures - small flux ropes - ought to be observed in conjunction with this event. We present such evidence here, and in particular use the curlometer technique to analyse the observations.
Kucharek H, Moebius E, Scholer M, et al., 2006, On the ion reflection properties of the quasi-perpendicular earth's bow shock, European Space Agency, (Special Publication) ESA SP, Pages: 299-304, ISSN: 0379-6566
Recent multiple spacecraft observations by Cluster revealed that field-aligned ion beams appear to emerge from the gyrating ions in the ramp of a quasiperpendicular shock created by the same reflection process. A closer look at recent findings show that effective scattering in pitch angle within the shock ramp during the reflection may also be needed to produce these beams at higher shock normal angles. Obviously, ion reflection, transmission and wave particle scattering depend on shock parameters, such as Mach number, plasma beta and shock angle. However, how important are these parameters relative to each other for these processes? Furthermore, the internal dynamics, structure of the shock and the cross-shock potential may also be important. A better understanding would provide very useful information about the ion reflection and transmission process at perpendicular shocks in general for other disciplines such as astrophysics. A survey of shock crossings for a wide range of plasma conditions such as shock normal angle, Mach number, and plasma beta has been compiled and investigated in detail in order to determine the major controlling parameters. In this database we included information about the cross shock potential and magnetic field profile at the shock, as well as the global dynamics of the shock. We will report on dependence of variability of different ion distributions such as the gyration and escaping ions on these various parameters.
