    Abstract
  • Magnetic reconnection on the magnetopause is a main way of energy transport from solar wind to magnetosphere.How magnetic reconnection is initiated is a hot yet unsolved topic in space physics research.However,on the magnetopause,it is difficult for a satellite to cross a site where reconnection is going on,and thus it is difficult to reveal the conditions which trigger magnetic reconnection.In this paper,a method is established to retrieve the locations of reconnection sites by using observations from THEMIS satellite.When reconnection initiates,the energy dispersion properties of ions ejected from the reconnection site can be observed by the satellite from a distance and are used to calculate the distance.The location of reconnection is then retrieved by tracing along modeled field lines for that distance.Our method is compared with other methods,and analyses indicate that our method may have higher accuracy than the others.
