Statistical characteristics of narrow-banded ELF emissions observed on board ISIS satellite
Occurrence distributions of narrow-banded ELF emissions over the southern polar region have been studied statistically from ISIS-1 and -2 VLF data which were received at Syowa Station (L=6.1) in Antarctica. It is found that emissions occurred mostly during the evening to the pre-midnight of 17-24 ML...
