Conjugate point Observation Syowa-Iceland
Conjugate observations of ELF-VLF emissions, geomagnetic pulsations and auroras were carried out at Syowa Station in Antarctica and at Husafell in Iceland from July 29, 1977 to September 18, 1977 Husafell is located at a distance of about 60 km from the conjugate point of Syowa From a prelimmary ana...
