Extended magnetic reconnection across the dayside magnetopause.
The extent of where magnetic reconnection (MR), the dominant process responsible for energy and plasma transport into the magnetosphere, operates across Earth's dayside magnetopause has previously been only indirectly shown by observations. We report the first direct evidence of X-line structure resulting from the operation of MR at each of two widely separated locations along the tilted, subso...
متن کاملCharacteristics of the near-tail dawn magnetopause and boundary layer
The paper discusses properties of the near-tail dawnside magnetopause and boundary layer, as obtained from Cluster plasma and magnetic field measurements during a single skimming orbit on 4 and 5 July 2001 that included 24 well-defined magnetopause crossings by all four spacecraft. As a result of variations of the interplanetary magnetic field, the magnetic shear across the local magnetopause v...
متن کاملFlux Transfer Events at the Dayside Magnetopause: Transient Reconnection or Magnetosheath Dynamic Pressure Pulses?
The suggestion isdiscussed that characteristic particle and field signatures at the dayside magnetopause, termed "flux transfer events" (FTEs), are, in at least some cases, due to transient solar wind and/or magnetosheath dynamic pressure increases, rather than timedependent magnetic reconnection. It is found that most individual cases of FTEs observed by a single spacecraft can, at least quali...
متن کاملDistinguishing between pulsed and continuous reconnection at the dayside magnetopause
Magnetic reconnection has been established as the dominant mechanism by which magnetic fields in different regions change topology to create open magnetic field lines that allow energy and momentum to flow into the magnetosphere. One of the persistent problems of magnetic reconnection is the question of whether the process is continuous or intermittent and what input condition(s) might favor on...
متن کاملMotion of the dayside polar cap boundary during substorm cycles: I. Observations of pulses in the magnetopause reconnection rate
Using data from the EISCAT (European Incoherent Scatter) VHF radar and DMSP (Defense Meteorological Satellite Program) spacecraft passes, we study the motion of the dayside open-closed field line boundary during two substorm cycles. The satellite data show that the motions of ion and electron temperature boundaries in EISCAT data, as reported by Moen et al. (2004), are not localised around the ...
