Magnetic holes(MHs)are structures observed in interplanetary space with significant decreases in the magnetic field *** using magnetic field and plasma data detected by Cluster,we have analyzed the magnetic field and plasma properties around the MHs and made comparisons with the average solar *** is found that the MHs seem likely to be occurred in the regions with relative lower magnetic field magnitude,higher ion density,larger plasma,and lower solar wind *** to the observations of the MHs associated with the ICMEs,it is found that about 10%of MHs related to ICMEs during the solar maximum,which may infer that the ICMEs may one possible source of the MHs during the solar *** in view of the occurrence rate of MHs has an increasing trend from the solar maximum to the solar minimum,it may indicate that the source other than ICME may contribute more to the MHs generated during the solar minimum.

Plasma energy dispersion properties inside reconnection jet flows observed inside the low-latitude boundary layer are used to determine the distances of observing satellites to reconnection *** locations of the reconnection sites are then retrieved by tracing the modeled field lines by those *** control ing effects of the dipole tilt angle to the location of X lines or reconnection sites are *** results show that the Earth’s dipole tilt angles strongly modify the location of X lines predicted by Cooling et al’s model,which is thought to be the result of magnetopause reshaping due to finite dipole tilt angles.
