Coordinated Ground-Satellite Observations of VLF Hiss Emissions at Syowa Station : Relationships between Hiss and Aurora
ISIS VLF data were received at Syowa Station, Antarctica in 1976. These data were compared with VLF and auroral data simultaneously observed on the around. In general, hiss and saucer emissions were succesively observed on ISIS 2, when ISIS 2 moved from the polar cap towards the low latitude. It is...
