Summary: 
In order to estimate the dynamic structure of the ionospheric exit points, we conducted ground-based observations of natural ELF/VLF waves at three unmanned sites around SHOWA station, Antarctica. For unmanned autonomous observations at the three sites, we developed three sets of new wave receivers. Three sets of receivers were installed in December 2005 and January 2006. After that our unmanned multipoint observations of natural ELF/VLF waves were stably running until January 2007. In this letter, we give a preliminary report of the multipoint observation results of natural ELF/VLF wave in Antarctica.
