| Zusammenfassung |
| Previous studies of magnetic reconnection in the solar wind have suggested that a single
reconnection X-line can extend and be active over millions of kilometres. We present a case
study of an event observed in the solar wind on the 2nd March 2006 by the four Cluster
spacecraft. We utilised the four point measurement capability to study the event at sub-second
resolution over separation distances of 10,000 km as well as over the larger scales
separating Cluster from ACE and WIND. We thus test the consistency of the temporal and
spatial structure of magnetic reconnection from large scales to small scales. This
reconnection event showed significant differences between the Cluster spacecraft,
particularly in the magnetic field data, suggesting reconnection in the solar wind can
be variable over relatively small temporal and or spatial scales (< 60 s and/or
~ 10,000 km). This leads to the conclusion that magnetic reconnection in the solar
wind is not necessarily large scale and may be patchy in nature. This result raises
questions about our current understanding of magnetic reconnection in the solar
wind. |
